[Dovecot] Antispam plugin + script sieve
by Allan Cassaro 27 Nov '08

27 Nov '08

Hi guys, I will start a little script that receive via antispam plugin an email, extract the "from" and "return-path" and create alter the sieve script of the user that send the e-mail. Well, I don't speak english very well (I speak like Borat!!!), but with some examples is better to understand: 1) Some user move an "undesirable" mail to "Automatic Block" folder 2) The antispam plugin call my script 3) The script parse the e-mail and extract the from and return-path mail 4) A rule is added to ~/.dovecot.sieve to dicard messages that came from that e-mail 5) If the user remove the mail from "Automatic Block" folder, the script remove this rule So, my question is: anyone is working on something similar with this? (I don't want to reinvent the wheel) Regards. -- "Não deixe a faculdade atrapalhar seus estudos." http://allan.cassaro.googlepages.com

[Dovecot] deliver segv on sieve redirect
by Andy Howell 27 Nov '08

27 Nov '08

Hello, I've been trying out the bleeding edge, 1.2.alpha4. I'm having a problem with deliver and dovecot-1.2-sieve-0.1.1. I get a segv on this sieve script: require ["fileinto", "reject", "vacation", "envelope", "regex"]; if header :contains "subject" ["urgent"] { redirect "someone(a)somewhere.net"; fileinto "test"; } Seems its happening on the "redirect". If I put the fileinto before the redirect, the fileinto works. I tried putting extra debug statements in plugins/lda-sieve/lda-sieve-plugin.c right after the sieve_execute in lda_sieve_run, but it never prints anything. I'm guessing thats the right place. Its quite possible there is something amiss in my setup. My logs show: Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: using sieve path: /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: opening script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin dovecot: deliver(andy(a)x.y.org): sieve: executing compiled script /var/mail/vhosts/x.y.org/andy/.dovecot.sieve Nov 26 02:51:12 marvin postfix/pipe[17027]: 0CA895CB3A: to=<andy(a)x.y.org>, relay=dovecot, delay=0.41, delays=0.33/0.01/0/0.07, dsn=5.3.0, status=bounced (Command died with signal 11: "/usr/libexec/dovecot/deliver") Thanks, Andy

[Dovecot] Released Sieve v0.1.2 (important bug fixed)
by Stephan Bosch 26 Nov '08

26 Nov '08

Hello Dovecot users, Today, Andy Howell tripped an important bug in the Sieve interpreter that makes it crash when redirect is executed. That is why I quickly release yet another new version to provide a fix for this bug. I really should prevent this from happening again in the future by extending the test suite to test the execution of actions. Changelog v0.1.2: - Fixed important bug in the redirect action (and probably other actions like reject and vacation that only send messages). This was a bug in the handling of context information during the execution of actions. It caused the sieve interpreter to crash with a segfault when redirect was executed. The release is available here: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.2.tar.gz.sig Refer to the initial release mail for more information: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] [OT] My appreciation for Dovecot
by Christoph Petersen 26 Nov '08

26 Nov '08

Hi guys! I recently switched to Dovecot from Courier with qmail+vpopmail backend. I'm really happy with the switch as all use-cases are more stable and much much faster than before. And the build process is much better as with Courier :) Just wanted to express my appreciation! BR Christoph

Interesting. Somebody else was reporting the same errors, but I'm not seeing them. But I'm still using 1.1.2. I'll review the changes, I guess, but if I don't find anything quickly I won't get around to poking at it before Christmas. johannes

[Dovecot] Unable to use imapflags in sieve
by Guillaume Hilt 25 Nov '08

25 Nov '08

Hello, I'm using dovecot 1.1.6 with libsieve 2.2.5 and I can't use the imapflags extension. Here's the begginning of my .dovecot.sieve file : require ["fileinto"]; #require "imapflags"; #require "reject"; #if header :contains "X-DSPAM-Probability: 0.9" { # addflag "$label3"; #} # On déplace le spam dans le dossier Spam et on s'arrête là if header :contains "X-DSPAM-Result" "Spam" { fileinto "Spam"; # addflag "\\Seen"; stop; } # Si le destinataire est l'user apache, on discarde le mail if address :is "to" "ftp(a)shadowprojects.fr" { discard; } # Listes de diffusion if header :contains "List-Id" "dovecot.dovecot.org" { fileinto "Listes.Dovecot"; stop; } If i enable imapflags (require ["fileinto","imapflags"];) sieve won't work anymore (same with reject by the way). Only enabling it without using it (with addflag) is enough to stop sieve from working. All my emails will be delivered in my inbox despite the rules I use. If I remove imapflags, everything is working fine. And I don't see anything in my logs explaining the problem.

[Dovecot] [dovecot] Pre-populate index files for mbox
by Jonathan Siegle 25 Nov '08

25 Nov '08

Is there a program written that can be used to build the index files for a given mbox file without using IMAP/POP? If not I'll be happy to donate it when I'm done. The args would be the userid , the full path to the mbox and where to put the index files. -Jonathan

[Dovecot] Released Sieve v0.1.1 and ManageSieve v0.11.2 for Dovecot v1.2.alpha4
by Stephan Bosch 25 Nov '08

25 Nov '08

Hello Dovecot users, Since the first release of the new Sieve implementation, not that many bugs were reported. This is probably due to the fact that it is not tried yet by that many people. In the mean time, I did find and fix some more bugs myself, I adapted to changes in Dovecot, wrote some more documentation and started work on the enotify extension. Both Sieve and ManageSieve were changed to match API changes in Dovecot and therefore older versions will not compile against the new Dovecot release. Likewise, these new Sieve and ManageSieve releases will not compile for older Dovecot versions. Changelog Sieve v0.1.1: * Re-enabled support for compiling against dovecot headers. Much like cmusieve, command line tools like sievec and sieved are not compiled in this case. * Started implementation of enotify extension. Not anywhere near finished though. * Adapted to changes in Dovecot on various occasions, making this release dependent on Dovecot >= v1.2.alpa4. + Improved logging of errors at specific occasions and added debug messages to find script execution problems quicker. + Removed code duplication between command line tools and the test suite. Also restructured the sources of the tools. + Added UTF-8 to UTF-7 folder name conversion for compatibility with IMAP. + Created man pages for the command line tools. These are automatically installed upon 'make install' + Incorporated Valgrind support into the test suite and fixed a few memory leaks in the process. - Fixed compile error surfacing for gcc3.4. Forgot mask argument for the open() system call when the O_CREAT flag is specified. Bug found by Sergey Ivanov. - Fixed bug in the sievec tool. -d output was always written to stdout. - Fixed important bug in the imap4flags extension. When no :flags argument is specified, the previous version would always use the final value of the internal variable to set the flags. This means that modifications to the internal variable also affected the bare fileinto/keep actions executed earlier. This does not comply to the RFC. - Fixed bug in the include extension's import/export commands. Duplicate import/exports caused problems. - Fixed bug in the handling of non-existent scripts. Errors were sometimes ignored. - Dovecot omitted unfolding multi-line headers. This was added to the cmusieve plugin after the code was incorporated into the new implementation. This is now implicitly fixed by concurrent change in Dovecot. Changelog ManageSieve v0.11.2: * Adapted to changes in Dovecot, making this release dependent on Dovecot >= v1.2.alpa4 The following files are released: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.1.tar.gz.sig ManageSieve package: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.2.tar.gz.s… ManageSieve patch: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.alpha4-managesieve-0.11.2.d… The full story of the new Sieve implementation is available in my previous posting: http://www.dovecot.org/list/dovecot-news/2008-October/000087.html I still need to update the wiki with pointers to the new Sieve implementation. I hope to have some time and motivation to do so in the next few days. Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] v1.1.7 released
by Timo Sirainen 25 Nov '08

25 Nov '08

http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.7.tar.gz.sig I should have released this earlier since v1.1.6 had that annoying startup problem, but surprisingly few people complained about it so I kind of forgot about it then. BTW. v1.2 progresses nicely. Now that shared mailboxes are finally fully supported, there aren't any widely used IMAP features missing from Dovecot. v1.2.beta1 shouldn't be in too distant future anymore. * IMAP QUOTA extension now returns "MESSAGE" quota, not "MESSAGES". This makes Dovecot now RFC 2087 compliant. Hopefully this change doesn't break anyone's Dovecot-specific quota checking code.. + Added !include and !include_try directives to config file reader. Note that !include doesn't currently work with deliver. The main point here is that ssl_key_password can be placed to a different file with !include_try that deliver can just ignore. + More error/debug message logging improvements. - v1.1.6 gave "userdb didn't return a home directory" error at startup - Some config file parsers (deliver, passwd-file, acl, trash) ignored the file's last line if it didn't end with LF. - fts: SEARCH SUBJECT didn't search messages that weren't already in fts index. - fts-solr: Don't assert-crash if we couldn't connect to Solr. - IMAP: Mailbox deletion gave an error, but still worked, if mails' control directory wasn't the same as index directory. - Several fixes to rarely used mailbox list layout configurations.
