Hi! I'm running 1.1rc4 on a system and this happens occasionally: --8<-- mail.info; dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=NN.NN.NN.NN rip=NNN.NN.NNN.NN lport=143 mail.info; dovecot: auth-worker(default): pam(XXXXXXXXXXXX,NNN.NN.NNN.NN): lookup service=imap kern.alert; kernel: grsec: From NN.NN.NN.NN: denied resource overstep by requesting 134242304 for RLIMIT_AS against limit 134217728 for /us authpriv.err; dovecot-auth: PAM unable to dlopen(/lib/security/pam_unix.so) authpriv.err; dovecot-auth: PAM [error: /lib/security/pam_unix.so: failed to map segment from shared object: Cannot allocate memory] authpriv.err; dovecot-auth: PAM adding faulty module: /lib/security/pam_unix.so mail.err; dovecot: auth-worker(default): pam(XXXXXXXXXXXX,NNN.NN.NNN.NN): pam_authenticate() failed: Authentication failure mail.info; dovecot: auth(default): new auth connection: pid=6262 mail.info; dovecot: auth(default): client out: FAIL 1 user=XXXXXXXXXXXX --8<-- When I restart dovecot, it runs fine for a while, then it starts happening again.

Re: [Dovecot] sa learning from an imap spam folder
by frank.kintrup＠fkware.de 11 Apr '08

This is my approach, stored in /etc/cron.hourly. It's very new, so I'm still testing it. The goal is to learn HAM massages only if they are a day old, so that I can manually remove SPAM that slipped through. Mails tagged from Spamassassin are sorted automatically into the "Junk.Spam" mailbox and learned after 12 hours. I manually move any missed SPAM into the .Junk mailbox, so I'm sure there are no wrongly tagged messages there, so I can learn those messages as soon as they are found by cron. /etc/cron.hourly/sa-learn: #!/bin/sh umask 022 # Learn HAM messages which were roughly received between 24 and 25 hours ago find \ /var/vmail/fkware.de/frank.kintrup/Maildir/ \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Junk*' -prune -o \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Sent' -prune -o \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Trash' -prune -o \ -path '/var/vmail/fkware.de/frank.kintrup/Maildir/.Draft' -prune -o \ -iname '*server.fkware.de*' -type f -mmin +1435 -mmin -1505 \ -execdir sa-learn --username=vmail --no-sync --ham {} \; \ /dev/nul 2>/dev/nul # Learn and delete SPAM messages which were manually moved to the Junk folder find \ /var/vmail/fkware.de/frank.kintrup/Maildir/.Junk/ \ -iname '*server.fkware.de*' -type f \ -execdir sa-learn --username=vmail --no-sync --spam {} \; \ -execdir rm {} \; \ >/dev/nul 2>/dev/nul # Learn and delete SPAM messages which were received more than 12 hours ago # and automatically put into the Junk.Spam folder find \ /var/vmail/fkware.de/frank.kintrup/Maildir/.Junk.Spam/ \ -iname '*server.fkware.de*' -type f -mmin +720 \ -execdir sa-learn --username=vmail --no-sync --spam {} \; \ -execdir rm {} \; \ >/dev/nul 2>/dev/nul sa-learn --username=vmail --sync >/dev/nul exit 0

[Dovecot] qmail + dovecot & vmail

Hi List, I have a working qmail server and installed dovecot trying to setup vmail... it's not going as expected... What is working: qmail I can log-in using Thunderbird (IMAP) from dovecot-info.log dovecot: Apr 10 21:19:54 Info: imap-login: Login: user=<peter(a)---.com>, method=PLAIN, rip=192.168.10.50, lip=192.168.10.188 Config bits: Ubuntu (command-line system) 7.10 ls -l /home drwxr-xr-- 2 vmail vmail ... vmail UID GID for vmail = 500 Content of /etc/dovecot/dovecot.conf protocols = imap imaps log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot-info.log ssl_disable = yes disable_plaintext_auth = no mail_location = maildir:~/Maildir dotlock_use_excl=yes maildir_copy_with_hardlinks=yes auth_verbose = yes auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd } userdb static { args = uid=500 gid=500 home=/home/vmail/%d/%n } } cat /etc/dovecot/passwd peter@meta-logica.com:{SSHA}iDMg--- peter@wilboo.org:{SSHA}iDMg--- cat /var/qmail/control/defaultdelivery |/var/qmail/bin/preline -f /usr/lib/dovecot/deliver -d $EXT@$USER (LWQ setup - verified location of 'deliver') Looks like local delivery for qmail is NOT working :-( from the logs: starting delivery 8: msg 3752525 to local peter@ma--- status: local 1/10 remote 0/20 delivery 8: deferral: Can't_open_log_file_/var/log/dovecot.log:_Permission_denied/ status: local 0/10 remote 0/20 status: exiting permission on /var/log/dovecot.log = -rw-r--r-- 1 vmail vmail 728 2008-04-10 21:36 /var/log/dovecot.log qmailctl stat messages in queue: 7 messages in queue but not yet preprocessed: 3 So I assume that the inability to 'log' is stopping the delivery process...

[Dovecot] Sieve Frustrations
by Shawn 11 Apr '08

11 Apr '08

I'm soooo close, but this last little thing is eluding me... I have the following Sieve rule in my global sieve rule: require ["fileinto"]; # Move spam to spam folder if header :contains "X-Spam-Flag" "YES" { fileinto "Junk"; stop; } This isn't firing. The .Junk folder exists under the user directories, but messages that have the X-Spam-Flag set are still going into INBOX. My personal Sieve rules are firing properly (now), so I know Sieve is operational. Just the global rule isn't being applied. If it helps, I set up my server according http://workaround.org/articles/ispmail-etch/ - but on a Ubuntu Gutsy server with only a few minor deviations from that article. My protocol lda section of dovecot.conf has this: log_path = /home/vmail/dovecot-deliver.log global_script_path = /home/vmail/globalsieverc I don't see any messages in dovecot-deliver.log that says there are problems with Sieve. The above rule is in /home/vmail/globalsieverc as mentioned here. This was working once - but when I had it going into the "spam" folder. I changed the folder name to match what ThunderBird sets up automagically for it's junk controls. But like I say, the directory does exist. So, I'm a little stumped. Any suggestions on where I can look to sort this out? If it helps, I've attached my dovecot conf (via dovecot -n) below. Thank you for your time!

[Dovecot] Procmail died with Signal 11
by Johannes Grimm 10 Apr '08

10 Apr '08

Hi to all out there, i know this is not the right mailinglist for this issue, but i?m hoping to get maybe here an answer to my problem. i have succesfully migrated 12.000 mailboxes on a debaian with washington imap to maildir on sles10 with dovecot. although i had some post-converting work to do, i can say that almost everything went fine. but there is one problem with my LDA. When postfix is about to deliver a lot of mail (user-db is ldap) procmail dies with signal 11. here is the error log: Apr 3 08:19:17 mailvirtuell postfix/local[22367]: E42EF33A96: to=<root(a)fh-rosenheim.de>, relay=local, delay=17, delays=0.08/0.11/0/17, dsn=5.3.0, status=bounced (Command died with signal 11: "IFS=` `&& exec /usr/bin/procmail || exit 75 #Ja". Command output: procmail: Exceeded LINEBUF ) I googled the whole inet for this problem and found a lot, but no solution seems to fit my problem. most articles point on this parameter for procmailrc "Linebuf". i found out that the default value is 2048k for message header reading. i doubled this value, with no effect. but i guess that a 4kb message header space must be enough to deal with. one hint last: starting value for ldap timeout was 10 secs. with this value the log went crazy like the above log-snip. i changed the timeout to 300 secs and thougt that was the trick, but there are still some process wich are diying after all. i?m using postfix 2.5.1, procmail 3.22, dovecot 1.0.13, with sophos and amavis. i would be really grateful for any ideas. best regards Johannes Grimm -- ============================================================== Hochschule für angewandte Wissenschaften - Fachhochschule Rosenheim University of Applied Sciences Rechenzentrum Johannes Grimm Hochschulstr.1 D-83024 Rosenheim Tel: +49-8031/805-229 Fax: +49-8031/805-223 http://www.fh-rosenheim.de/ johannes.grimm(a)fh-rosenheim.de ==============================================================

[Dovecot] Delete old mails and refresh quota
by Nicolas Letellier 09 Apr '08

09 Apr '08

Hello. I use dovecot 1.0.13. So, I can't use expire plugin (require dovecot 1.1+). For delete old mails in Junk mailboxe, I use a cron: find /var/mail/vmails/ -regex '.*Junk/cur/.*' -ctime +30 -delete It works. However, quota is not refreshed. If my quota is to 90% and I delete 85% of my mails, quota still 90%, not 5%. I must delete my maildirsize after this cron. Do you have another solution to actualisize my maildirsize after a delete of mail? Thanks! - Nicolas.
