[Dovecot] feature request for managesieve build from packager
by seriv＠parkheights.dyndns.org 02 Nov '08

02 Nov '08

Hi everybody, dovecot-1.2 alpha3 with cmusieve, libsieve and managesieve are available as rpm packages for Sisyphus repository (http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus, and specs/patches are available at http://git.altlinux.org/people/seriv/packages/?p=dovecot.git and http://git.altlinux.org/people/seriv/packages/?p=dovecot-sieve.git) Thank you very much Timo and Stephan! I have a feature-request for managesieve configure and Makefiles: they depend on dovecot sources as they are used for build process. I think it would be very nice to have not just --with-dovecot parameter in configure parameters, but also --with-dovecot-includes and --with-dovecot-libs. The same about cmusieve plugin: dovecot has --enable-header-install parameter, but installed headers are not sufficient for building cmusieve, I need install libraries and then modify cmusieve's Makefiles by running something like: --- for f in `find . -name Makefile` do mv -f $f $f.orig sed -e's/\$(dovecotdir)\/src$\/lib\/.*\.a$/\$(libdir)\/dovecot\/modules\1/g' \ < $f.orig > $f done --- before make in %build section. -- With best regards, Sergey Ivanov.

[Dovecot] imap processes eating IO
by Ryan Rawdon 02 Nov '08

02 Nov '08

[Ignore the previous e-mail, I somehow sent it when I was trying to paste from clipboard] I recently migrated my dovecot/postfix setup to a new machine. After doing so, I have encountered a problem where imap processes get stuck in a loop eating loads of IO on the machine. Looking at the trace (snippet below), it looks like they are sitting and reading the inbox and other folders of certain users repeatedly. This seems to be triggered by the delivery of a new e-mail to the user's mailbox while they have an IMAP client connected, though I cannot say for sure. This had never happened before on the old machine. I'm certain more information would be useful, please let me know what I can provide to help! Trace of process 22342 - imap lstat64("/home/vmail/u13.net/ryan/Maildir/cur/1203440140.P6242Q0M41485.scarecrow:2,RSc", {st_mode=S_IFREG|0600, st_size=3079, ...}) = 0

[Dovecot] antispam plugin problem
by Eugene 01 Nov '08

01 Nov '08

Hi people! (Especially Johannes, probably =) I recently switched to DSPAM + antispam plugin combination. Mostly I am happy but there is a problem with calling dspam-exec in order to relearn the messages. Moving messages to spam folder does not work, giving the error message 'Failed to call dspam' to client. I tried to add some debug output and here are the results: This is the output of debug("calling dspam: %s %s %s %s %s %s %s", argv[0], argv[1], argv[2], argv[3], argv[4], argv[5], argv[6]); (debugv(argv) does not produce any output for some reason) Oct 26 02:37:12 qqqqq imap: antispam: calling dspam: /usr/contrib/bin/dspam --source=error --class=spam --signature=490387db858421194018847 --user genie (null) This is the captured output of forked process Oct 26 02:37:12 qsar imap: antispam: dspam returned: ^APdata stack: Out of memory when allocating 1073741840 bytes If I understand correctly, this message is produced by dovecot before it should have launched dspam executable. I don't know why it needs 1GB of stack space for that. Changing dspam to dspamc does not help. Interestingly enough, launching 'sendmail' in mailtrain mode works ok. Do you have any ideas about what is wrong? Best wishes Eugene

[Dovecot] dovecot expire doesn't work (?)
by LÉVAI Dániel 31 Oct '08

31 Oct '08

Hi! I'm using dovecot-1.1.5 and trying to make the expire plugin work. What I've configured in dovecot.conf is the following: protocol imap,pop3,lda { mail_plugins = [...] expire } dict { expire = db:/var/dovecot/expire/expire.db } plugin { expire = spamassassin/SPAM 2 spamassassin/HAM 2 expire_dict = proxy::expire } I have a sieve rule, to copy certain messages to my "spamassassin/SPAM" folder. Then I want to expire those messages after 2 days (I think I've configured that under the plugin{} section in dovecot.conf). So the actual message saving is done by the dovecot's deliver, but I have the plugin loaded under the "protocol lda {}" section too. So I thought now I just have to wait 2 days, and run the expire-tool, and then it will expire the messages. Now I have three messages dated back to 10.25, but running the expire-tool outputs nothing. # dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool --test Nothing in the logfiles, and nothing on the console. I have the /var/dovecot/expire directory: # ls -la /var/dovecot/expire/ total 1640 drwx------ 2 root wheel 512 Oct 26 19:47:53 2008 ./ drwxr-x--- 3 root wheel 512 Oct 27 07:57:42 2008 ../ -rw------- 1 root wheel 24576 Oct 27 13:00:01 2008 __db.001 -rw------- 1 root wheel 57344 Oct 27 13:00:01 2008 __db.002 -rw------- 1 root wheel 270336 Oct 27 13:00:01 2008 __db.003 -rw------- 1 root wheel 98304 Oct 27 13:00:01 2008 __db.004 -rw------- 1 root wheel 49152 Oct 27 13:00:01 2008 __db.005 -rw------- 1 root wheel 32768 Oct 26 19:47:37 2008 expire.db -rw------- 1 root wheel 10485760 Oct 27 14:22:08 2008 log.0000000001 It contains the familiar BDB files, so I think it works, although the expire.db's modify time is yesterday, but deliver saved some messages also today to the spamassassin/SPAM folder. What could be the problem? Am I missing something? Thanks! Daniel -- LEVAI Daniel PGP key ID = 0x4AC0A4B1 Key fingerprint = D037 03B9 C12D D338 4412 2D83 1373 917A 4AC0 A4B1

[Dovecot] Problem with Dovecot 1.1.4 and dovecot-antispam 20080829
by Guillaume Hilt 31 Oct '08

31 Oct '08

Hi there, I'm running a server under Gentoo 64 with postfix 2.5.5, Dovecot 1.1.4-r1 and Dovecot-antispam 20080829 (all are the lastest versions availables under Portage). I ran into a problem when I log in to my mailbox : Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Loading modules from directory: /usr/lib64/dovecot/imap Oct 30 10:39:23 ks29138 dovecot: IMAP(hiltg): Module is for different version 1.1.1: /usr/lib64/dovecot/imap/lib90_antispam_plugin.so Oct 30 10:39:23 ks29138 dovecot: Fatal: IMAP(hiltg): Couldn't load required plugins Is there another version for Dovecot 1.1.4 out there or must I go back to 1.1.1 ? Thanks, Guillaume

[Dovecot] Dovecot read only for users
by JC 31 Oct '08

31 Oct '08

All, I have hopefully a base question. How do you give users only read access to their inbox and folders? If I use chmod 600 they have full access. If I do a 400 they have read access but cannot access their inbox. The config file is the out of the box config other than advertising IMAP and IMAPS. Any help will be appreciated. Thanks.
