In my case, the cause was a large spam message (above the configured MaxMessageSize parameter for DSPAM) that was skipped during tests and thus no signature was added. Might this be true in your case? As a general suggestion for Johannes: maybe it is better to ignore this error silently, just move the message and don't call DSPAM? > I checked that the given location for the dspam executable is correct, > that the user executing it (dovecot?) is actually able to execute dspam > and that dspam trusts this user.

I have lines like > X-DSPAM-Signature: 1,49084a24139132188715614 Another guess: if that comma is not a misprint, something is wrong in your setup. Regards Eugene

[Dovecot] Can I import RFC822 messages into Dovecot from file system
by bbell2000 27 Nov '08

27 Nov '08

I'm returning to qmail and dovecot after having suffered a complete failure with a different mail system and I'm now trying to figure out the easiest way to recover our messages from the failed system. The messages are stored as RFC822 in individual files and I can easily identify which message belongs to whom. I have qmail and dovecot configured to use Maildir format. I know I can probably write a script that resends the messages... but in addition to adding another layer of transport headers I really don't want, it's going to be way slow unless I disable my current content filters. I'm new to dovecot and what's got me hung up are the indexes that dovecot maintains in each user's directory. Otherwise, I'd probably try copying the messages into Maildir/cur just to see if it worked. I could sure use some ideas about an efficient, reliable means of getting our old messages back. Thanks. -- View this message in context: http://www.nabble.com/Can-I-import-RFC822-messages-into-Dovecot-from-file-s… Sent from the Dovecot mailing list archive at Nabble.com.

[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
