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

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] 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.

[Dovecot] Newbie Sieve Problems
by Shawn 09 Apr '08

09 Apr '08

I had a nice long email written out describing my problem in detail. Between that, the list archives, and double-checking before posting, I'm happy to say my issue seems to be fixed. How's that for service from a mailing list? Helped me fix a problem before I have ever posted to it (this is my first post to this list). The issue was a faulty rule. Using a redirect to a folder rather than a fileinto. Guess it was still sorta valid though cuz I did run it through a sieve rule checker. Thanks list! Shawn

[Dovecot] dovecot and postfix virtual mailbox domains
by Dave 08 Apr '08

08 Apr '08

Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username, there's a maildir under that. In this case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account and being completely virtual. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd I'd appreciate any pointers. I think i am close, but am not seeing it. Thanks. Dave.

[Dovecot] feature request: deny IP address via database
by Dave McGuire 08 Apr '08

08 Apr '08

Hey folks. One feature I'd really like to see in dovecot is the ability to point it at a database (with a configurable query) and have it allow or deny a connection based on looking up the source IP address in that database. I run Postfix, and I've got it configured to use a database server for its smtpd_client_restrictions checks. Ideally I'd like to point dovecot at the same database table. I have external tools that maintain that table. I was thinking of writing it myself, but I'm running 1.0.10; I'd assume that any such modifications would need to be rewritten for 1.1. Then I got to thinking that such functionality would likely be useful to people other than just me, so.. Thoughts? -Dave -- Dave McGuire Port Charlotte, FL

Re: [Dovecot] feature request: deny IP address via database
by Javier García 08 Apr '08

Written by Bill Cole on Apr 7, 2008, at 4:58 PM: >> Hey folks. One feature I'd really like to see in dovecot is the >> ability to point it at a database (with a configurable query) and >> have it allow or deny a connection based on looking up the source >> IP address in that database. ... much stuff discarded. I understand that the behaviour requested is similar to that of allow_nets (http://wiki.dovecot.org/PasswordDatabase/ExtraFields/AllowNets) but modified to explicitly deny some IPs (individually or in the range form). If so, probably some of the work should be already done. Sorry, I do not have the programming abilities enough to face this. Incidentally, I would like to notice that I opened a thread a few days ago regarding allow_nets and database (Bill's request needs to make use of an external database too) because I am not able to make allow_nets work properly when using an external DB *and IP ranges*. Maybe Bill would like to block single IPs so this bug? wold not apply to his case if an extension or adaptation of allow_nets is done. (My request, in case someone out there is curious: "Allow_nets + MySQL failing when using range notation") Regards, Javier

[Dovecot] A little assistance with Sieve
by cam＠ellisonpsychology.ca 07 Apr '08

07 Apr '08

With all the mess that my email has become, it makes sense for me to try to make use of Sieve, but I'm having quite the time finding out how to make it work. I'm running 1.0.13 on a Debian machine. Sieve appears to be compiled with it. I can access managesieve, and I have set up dovecot.conf with lda. I do not get a NO response when I PUTSCRIPI, but LISTSCRIPTS produces no result, so I assume it's not working properly, though if I try with a non-existent script I get an error message. Questions: 1. Is anyone else seeing this, or am I doing something wrong? 2. I have seen through Googling some dovecot.conf examples that suggest I should be using managesieve instead of lda (or in addition? - it's not clear), as in protocol managesieve { ... Any advice will be gratefully received.

[Dovecot] Problem with dovecot under Vmware Server
by Marvin Raab 06 Apr '08

06 Apr '08

Hi all, Recently installed dovecot and postfix under Fedora8 and it works great. Then I installed both postfix and dovecot under VMWare Server (different machine) copying the same configuration files but changing the hostname and domain as appropriate. When testing the installation using: telnet hostname 143, I receive * OK Dovecot ready But when I telnet on port 25, I receive: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. Instead of: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. 220 mail.kickspam.net ESMTP Postfix Naturally, I cannot send email. Outlook responds with Server timeout. I've rebooted and restarted services. I've checked poermissions and postfix master.cf How can I troubleshoot or does anyone have a quick answer? Thanks! Here's the output of dovecot -n and postconf -n The same config files are on both hosts and only the installation under VMWare Server has the problem.

[Dovecot] Broken Debian package
by Thing 06 Apr '08

06 Apr '08

Hi, I have run Dovecot via Debian for some years but in the last few weeks something has broken....I have been upgrading Debian but today rebooted it to try and sort out a failed DLT....now I find dovecot is non-functional.... So, Where to look for faults please? ie logs? can I make dovecot verbose? Thunderbird if telling me Dovecot is not imap4 compliant........and I cannot connect to it... I have tried re-installing Dovecot but the Debian package contains no dovecot.conf....so I have dovecot imap-d and dovecot common installed but no config. So I copied back the config files from a safe location.... When I start up I get, hermes:/var/log# tail dovecot dovecot: 2008-04-06 11:32:32 Info: Dovecot v1.0.rc15 starting up hermes:/var/log# So trying to connect, tail -f (on /var/log/dovecot), dovecot: 2008-04-06 11:57:34 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:34 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:34 Error: child 20048 (imap) killed with signal 6 dovecot: 2008-04-06 11:57:34 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:34 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:34 Error: child 20050 (imap) killed with signal 6 dovecot: 2008-04-06 11:57:34 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:34 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:34 Error: child 20052 (imap) killed with signal 6 dovecot: 2008-04-06 11:57:35 Info: imap-login: Login: user=<phoebe>, method=PLAIN, rip=192.168.1.102, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:35 Info: imap-login: Login: user=<thing>, method=plain, rip=192.168.1.101, lip=192.168.1.254, TLS dovecot: 2008-04-06 11:57:35 Error: IMAP(thing): seq = 186, rec->uid = 0, first_new_seq = 188, records = 187 dovecot: 2008-04-06 11:57:35 Error: child 20062 (imap) killed with signal 6 squirrelmail is also now dead....
