Sieve Support for Emacs This manual documents the Emacs Sieve package. It is intended as a users manual for Sieve Mode and Manage Sieve, and as a reference manual for the ‘sieve-manage’ protocol Emacs Lisp API. Sieve is a language for server-side filtering of mail. The language is documented in RFC 3028. This manual does not attempt to document the language, so keep RFC 3028 around. A good online Sieve resources is http://www.cyrusoft.com/sieve/. Installation Install Setup The Sieve package should come with your Emacs version, and should be ready for use directly. However, to manually set up the package you can put the following commands in your ~/.emacs:(autoload 'sieve-mode "sieve-mode")(setq auto-mode-alist (cons '("\\.s\\(v\\|iv\\|ieve\\)\\'" . sieve-mode) auto-mode-alist)) Sieve Mode Sieve mode provides syntax-based indentation, font-locking support and other handy functions to make editing Sieve scripts easier. Use ‘M-x sieve-mode’ to switch to this major mode. This command runs the hook sieve-mode-hook. sieve-mode-map sieve-mode-syntax-table Sieve mode is derived from c-mode, and is very similar except for the syntax of comments. The keymap (sieve-mode-map) is inherited from c-mode, as are the variables for customizing indentation. Sieve mode has its own abbrev table (sieve-mode-abbrev-table) and syntax table (sieve-mode-syntax-table). In addition to the editing utility functions, Sieve mode also contains bindings to manage Sieve scripts remotely. See . C-c RET C-c RET sieve-manage manage remote sieve scriptOpen a connection to a remote server using the Managesieve protocol. C-c C-l C-c C-l sieve-upload upload sieve scriptUpload the Sieve script to the currently open server. Managing Sieve Manage Sieve is a special mode used to display Sieve scripts available on a remote server. It can be invoked with M-x sieve-manage RET, which queries the user for a server and if necessary, user credentials to use. When a server has been successfully contacted, the Manage Sieve buffer looks something like: Server : mailserver:2000 2 scripts on server, press RET on a script name edits it, or press RET on <new script> to create a new script. <new script> ACTIVE .sieve template.siv One of the scripts are highlighted, and standard point navigation commands (<up>, <down> etc) can be used to navigate the list. The following commands are available in the Manage Sieve buffer: m m sieve-activateActivates the currently highlighted script. u u sieve-deactivateDeactivates the currently highlighted script. C-M-? C-M-? sieve-deactivate-allDeactivates all scripts. r r sieve-removeRemove currently highlighted script. RETmouse-2f RET mouse-2 f sieve-edit-scriptBury the server buffer and download the currently highlighted scriptinto a new buffer for editing in Sieve mode (see ). o o sieve-edit-script-other-windowCreate a new buffer in another window containing the currentlyhighlighted script for editing in Sieve mode (see ). q q sieve-bury-bufferBury the Manage Sieve buffer without closing the connection. ?h ? h sieve-helpDisplays help in the minibuffer. Examples If you are not familiar with Sieve, this chapter contains a few simple code snippets that you can cut'n'paste and modify at will, until you feel more comfortable with the Sieve language to write the rules from scratch. The following complete Sieve script places all messages with a matching ‘Sender:’ header into the given mailbox. Many mailing lists uses this format. The first line makes sure your Sieve server understands the fileinto command. require "fileinto"; if address "sender" "owner-w3-beta@xemacs.org" { fileinto "INBOX.w3-beta"; } A few mailing lists do not use the ‘Sender:’ header, but does contain some unique identifier in some other header. The following is not a complete script, it assumes that fileinto has already been required. if header :contains "Delivered-To" "auc-tex@sunsite.dk" { fileinto "INBOX.auc-tex"; } At last, we have the hopeless mailing lists that does not have any unique identifier and you are forced to match on the ‘To:’ and ‘Cc’ headers. As before, this snippet assumes that fileinto has been required. if address ["to", "cc"] "kerberos@mit.edu" { fileinto "INBOX.kerberos"; } Manage Sieve API The sieve-manage.el library contains low-level functionality for talking to a server with the managesieve protocol. A number of user-visible variables exist, which all can be customized in the sieve group (M-x customize-group RET sieve RET): sieve-manage-default-user sieve-manage-default-userSets the default username. sieve-manage-default-port sieve-manage-default-portSets the default port to use, the suggested port number is 2000. sieve-manage-log sieve-manage-logIf non-nil, should be a string naming a buffer where a protocol traceis dumped (for debugging purposes). The API functions include: sieve-manage-open sieve-manage-openOpen connection to managesieve server, returning a buffer to be usedby all other API functions. sieve-manage-opened sieve-manage-openedCheck if a server is open or not. sieve-manage-close sieve-manage-closeClose a server connection. sieve-manage-authenticate sieve-manage-authenticateAuthenticate to the server. sieve-manage-capability sieve-manage-capabilityReturn a list of capabilities the server support. sieve-manage-listscripts sieve-manage-listscriptsList scripts on the server. sieve-manage-havespace sieve-manage-havespaceReturns non-nil iff server have roam for a script of givensize. sieve-manage-getscript sieve-manage-getscriptDownload script from server. sieve-manage-putscript sieve-manage-putscriptUpload script to server. sieve-manage-setactive sieve-manage-setactiveIndicate which script on the server should be active. Standards The Emacs Sieve package implements all or parts of a small but hopefully growing number of RFCs and drafts documents. This chapter lists the relevant ones. They can all be fetched from http://quimby.gnus.org/notes/.

Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. PREAMBLEThe purpose of this License is to make a manual, textbook, or otherfunctional and useful document “free” in the sense of freedom: toassure everyone the effective freedom to copy and redistribute it,with or without modifying it, either commercially or noncommercially.Secondarily, this License preserves for the author and publisher a wayto get credit for their work, while not being considered responsiblefor modifications made by others.This License is a kind of “copyleft,” which means that derivativeworks of the document must themselves be free in the same sense. Itcomplements the GNU General Public License, which is a copyleftlicense designed for free software.We have designed this License in order to use it for manuals for freesoftware, because free software needs free documentation: a freeprogram should come with manuals providing the same freedoms that thesoftware does. But this License is not limited to software manuals;it can be used for any textual work, regardless of subject matter orwhether it is published as a printed book. We recommend this Licenseprincipally for works whose purpose is instruction or reference. APPLICABILITY AND DEFINITIONSThis License applies to any manual or other work, in any medium, thatcontains a notice placed by the copyright holder saying it can bedistributed under the terms of this License. Such a notice grants aworld-wide, royalty-free license, unlimited in duration, to use thatwork under the conditions stated herein. The “Document,” below,refers to any such manual or work. Any member of the public is alicensee, and is addressed as “you.” You accept the license if youcopy, modify or distribute the work in a way requiring permissionunder copyright law.A “Modified Version” of the Document means any work containing theDocument or a portion of it, either copied verbatim, or withmodifications and/or translated into another language.A “Secondary Section” is a named appendix or a front-matter section ofthe Document that deals exclusively with the relationship of thepublishers or authors of the Document to the Document's overall subject(or to related matters) and contains nothing that could fall directlywithin that overall subject. (Thus, if the Document is in part atextbook of mathematics, a Secondary Section may not explain anymathematics.) The relationship could be a matter of historicalconnection with the subject or with related matters, or of legal,commercial, philosophical, ethical or political position regardingthem.The “Invariant Sections” are certain Secondary Sections whose titlesare designated, as being those of Invariant Sections, in the noticethat says that the Document is released under this License. If asection does not fit the above definition of Secondary then it is notallowed to be designated as Invariant. The Document may contain zeroInvariant Sections. If the Document does not identify any InvariantSections then there are none.The “Cover Texts” are certain short passages of text that are listed,as Front-Cover Texts or Back-Cover Texts, in the notice that says thatthe Document is released under this License. A Front-Cover Text maybe at most 5 words, and a Back-Cover Text may be at most 25 words.A “Transparent” copy of the Document means a machine-readable copy,represented in a format whose specification is available to thegeneral public, that is suitable for revising the documentstraightforwardly with generic text editors or (for images composed ofpixels) generic paint programs or (for drawings) some widely availabledrawing editor, and that is suitable for input to text formatters orfor automatic translation to a variety of formats suitable for inputto text formatters. A copy made in an otherwise Transparent fileformat whose markup, or absence of markup, has been arranged to thwartor discourage subsequent modification by readers is not Transparent.An image format is not Transparent if used for any substantial amountof text. A copy that is not “Transparent” is called “Opaque.”Examples of suitable formats for Transparent copies include plainASCII without markup, Texinfo input format, LaTeX input format, SGMLor XML using a publicly available DTD, and standard-conforming simpleHTML, PostScript or PDF designed for human modification. Examples oftransparent image formats include PNG, XCF and JPG. Opaque formatsinclude proprietary formats that can be read and edited only byproprietary word processors, SGML or XML for which the DTD and/orprocessing tools are not generally available, and themachine-generated HTML, PostScript or PDF produced by some wordprocessors for output purposes only.The “Title Page” means, for a printed book, the title page itself,plus such following pages as are needed to hold, legibly, the materialthis License requires to appear in the title page. For works informats which do not have any title page as such, “Title Page” meansthe text near the most prominent appearance of the work's title,preceding the beginning of the body of the text.A section “Entitled XYZ” means a named subunit of the Document whosetitle either is precisely XYZ or contains XYZ in parentheses followingtext that translates XYZ in another language. (Here XYZ stands for aspecific section name mentioned below, such as “Acknowledgements,”“Dedications,” “Endorsements,” or “History.”) To “Preserve the Title”of such a section when you modify the Document means that it remains asection “Entitled XYZ” according to this definition.The Document may include Warranty Disclaimers next to the notice whichstates that this License applies to the Document. These WarrantyDisclaimers are considered to be included by reference in thisLicense, but only as regards disclaiming warranties: any otherimplication that these Warranty Disclaimers may have is void and hasno effect on the meaning of this License. VERBATIM COPYINGYou may copy and distribute the Document in any medium, eithercommercially or noncommercially, provided that this License, thecopyright notices, and the license notice saying this License appliesto the Document are reproduced in all copies, and that you add no otherconditions whatsoever to those of this License. You may not usetechnical measures to obstruct or control the reading or furthercopying of the copies you make or distribute. However, you may acceptcompensation in exchange for copies. If you distribute a large enoughnumber of copies you must also follow the conditions in section 3.You may also lend copies, under the same conditions stated above, andyou may publicly display copies. COPYING IN QUANTITYIf you publish printed copies (or copies in media that commonly haveprinted covers) of the Document, numbering more than 100, and theDocument's license notice requires Cover Texts, you must enclose thecopies in covers that carry, clearly and legibly, all these CoverTexts: Front-Cover Texts on the front cover, and Back-Cover Texts onthe back cover. Both covers must also clearly and legibly identifyyou as the publisher of these copies. The front cover must presentthe full title with all words of the title equally prominent andvisible. You may add other material on the covers in addition.Copying with changes limited to the covers, as long as they preservethe title of the Document and satisfy these conditions, can be treatedas verbatim copying in other respects.If the required texts for either cover are too voluminous to fitlegibly, you should put the first ones listed (as many as fitreasonably) on the actual cover, and continue the rest onto adjacentpages.If you publish or distribute Opaque copies of the Document numberingmore than 100, you must either include a machine-readable Transparentcopy along with each Opaque copy, or state in or with each Opaque copya computer-network location from which the general network-usingpublic has access to download using public-standard network protocolsa complete Transparent copy of the Document, free of added material.If you use the latter option, you must take reasonably prudent steps,when you begin distribution of Opaque copies in quantity, to ensurethat this Transparent copy will remain thus accessible at the statedlocation until at least one year after the last time you distribute anOpaque copy (directly or through your agents or retailers) of thatedition to the public.It is requested, but not required, that you contact the authors of theDocument well before redistributing any large number of copies, to givethem a chance to provide you with an updated version of the Document. MODIFICATIONSYou may copy and distribute a Modified Version of the Document underthe conditions of sections 2 and 3 above, provided that you releasethe Modified Version under precisely this License, with the ModifiedVersion filling the role of the Document, thus licensing distributionand modification of the Modified Version to whoever possesses a copyof it. In addition, you must do these things in the Modified Version:A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.C. State on the Title page the name of the publisher of the Modified Version, as the publisher.D. Preserve all the copyright notices of the Document.E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice.H. Include an unaltered copy of this License.I. Preserve the section Entitled “History,” Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.K. For any section Entitled “Acknowledgements” or “Dedications,” Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles.M. Delete any section Entitled “Endorsements.” Such a section may not be included in the Modified Version.N. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section.O. Preserve any Warranty Disclaimers.If the Modified Version includes new front-matter sections orappendices that qualify as Secondary Sections and contain no materialcopied from the Document, you may at your option designate some or allof these sections as invariant. To do this, add their titles to thelist of Invariant Sections in the Modified Version's license notice.These titles must be distinct from any other section titles.You may add a section Entitled “Endorsements,” provided it containsnothing but endorsements of your Modified Version by variousparties–for example, statements of peer review or that the text hasbeen approved by an organization as the authoritative definition of astandard.You may add a passage of up to five words as a Front-Cover Text, and apassage of up to 25 words as a Back-Cover Text, to the end of the listof Cover Texts in the Modified Version. Only one passage ofFront-Cover Text and one of Back-Cover Text may be added by (orthrough arrangements made by) any one entity. If the Document alreadyincludes a cover text for the same cover, previously added by you orby arrangement made by the same entity you are acting on behalf of,you may not add another; but you may replace the old one, on explicitpermission from the previous publisher that added the old one.The author(s) and publisher(s) of the Document do not by this Licensegive permission to use their names for publicity for or to assert orimply endorsement of any Modified Version. COMBINING DOCUMENTSYou may combine the Document with other documents released under thisLicense, under the terms defined in section 4 above for modifiedversions, provided that you include in the combination all of theInvariant Sections of all of the original documents, unmodified, andlist them all as Invariant Sections of your combined work in itslicense notice, and that you preserve all their Warranty Disclaimers.The combined work need only contain one copy of this License, andmultiple identical Invariant Sections may be replaced with a singlecopy. If there are multiple Invariant Sections with the same name butdifferent contents, make the title of each such section unique byadding at the end of it, in parentheses, the name of the originalauthor or publisher of that section if known, or else a unique number.Make the same adjustment to the section titles in the list ofInvariant Sections in the license notice of the combined work.In the combination, you must combine any sections Entitled “History”in the various original documents, forming one section Entitled“History”; likewise combine any sections Entitled “Acknowledgements,”and any sections Entitled “Dedications.” You must delete all sectionsEntitled “Endorsements.” COLLECTIONS OF DOCUMENTSYou may make a collection consisting of the Document and other documentsreleased under this License, and replace the individual copies of thisLicense in the various documents with a single copy that is included inthe collection, provided that you follow the rules of this License forverbatim copying of each of the documents in all other respects.You may extract a single document from such a collection, and distributeit individually under this License, provided you insert a copy of thisLicense into the extracted document, and follow this License in allother respects regarding verbatim copying of that document. AGGREGATION WITH INDEPENDENT WORKSA compilation of the Document or its derivatives with other separateand independent documents or works, in or on a volume of a storage ordistribution medium, is called an “aggregate” if the copyrightresulting from the compilation is not used to limit the legal rightsof the compilation's users beyond what the individual works permit.When the Document is included in an aggregate, this License does notapply to the other works in the aggregate which are not themselvesderivative works of the Document.If the Cover Text requirement of section 3 is applicable to thesecopies of the Document, then if the Document is less than one half ofthe entire aggregate, the Document's Cover Texts may be placed oncovers that bracket the Document within the aggregate, or theelectronic equivalent of covers if the Document is in electronic form.Otherwise they must appear on printed covers that bracket the wholeaggregate. TRANSLATIONTranslation is considered a kind of modification, so you maydistribute translations of the Document under the terms of section 4.Replacing Invariant Sections with translations requires specialpermission from their copyright holders, but you may includetranslations of some or all Invariant Sections in addition to theoriginal versions of these Invariant Sections. You may include atranslation of this License, and all the license notices in theDocument, and any Warranty Disclaimers, provided that you also includethe original English version of this License and the original versionsof those notices and disclaimers. In case of a disagreement betweenthe translation and the original version of this License or a noticeor disclaimer, the original version will prevail.If a section in the Document is Entitled “Acknowledgements,”“Dedications,” or “History,” the requirement (section 4) to Preserveits Title (section 1) will typically require changing the actualtitle. TERMINATIONYou may not copy, modify, sublicense, or distribute the Document exceptas expressly provided for under this License. Any other attempt tocopy, modify, sublicense or distribute the Document is void, and willautomatically terminate your rights under this License. However,parties who have received copies, or rights, from you under thisLicense will not have their licenses terminated so long as suchparties remain in full compliance. FUTURE REVISIONS OF THIS LICENSEThe Free Software Foundation may publish new, revised versionsof the GNU Free Documentation License from time to time. Such newversions will be similar in spirit to the present version, but maydiffer in detail to address new problems or concerns. Seehttp://www.gnu.org/copyleft/.Each version of the License is given a distinguishing version number.If the Document specifies that a particular numbered version of thisLicense “or any later version” applies to it, you have the option offollowing the terms and conditions either of that specified version orof any later version that has been published (not as a draft) by theFree Software Foundation. If the Document does not specify a versionnumber of this License, you may choose any version ever published (notas a draft) by the Free Software Foundation. ADDENDUM: How to use this License for your documents To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (C) year your name. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License.'' If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with...Texts.” line with this: with the Invariant Sections being list their titles, with the Front-Cover Texts being list, and with the Back-Cover Texts being list. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software. xreflabel="Index" id="Index"> Index I Install, see M manage remote sieve script, see S Setup, see sieve-activate, see sieve-bury-buffer, see sieve-deactivate, see sieve-deactivate-all, see sieve-edit-script, see sieve-edit-script-other-window, see sieve-help, see sieve-manage, see sieve-manage-authenticate, see sieve-manage-capability, see sieve-manage-close, see sieve-manage-default-port, see sieve-manage-default-user, see sieve-manage-getscript, see sieve-manage-havespace, see sieve-manage-listscripts, see sieve-manage-log, see sieve-manage-open, see sieve-manage-opened, see sieve-manage-putscript, see sieve-manage-setactive, see sieve-mode-map, see sieve-mode-syntax-table, see sieve-remove, see sieve-upload, see U upload sieve script, see
