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...

[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 ==============================================================
