[Dovecot] maildir filename with eg. ,S=1000, omitted
by Joseph LP 20 May '09

20 May '09

Hello. I encountered the wiki entry on maildirs not long ago. In it, it is suggested that the use of ,S= and ,W= may improve performance as dovecot does not need to calculate size itself. While my maildir filenames have ,W=, they lack ,S=. I've grepped dovecot.conf, but I can find no option to address this. Regards, Joseph

[Dovecot] %d isn't expanded

Hi all I have a box running Debian Lenny 5.0.1 and Dovecot 1.0.15. The user query given below does not expand %d, making logins fail. The password query seems to work well, according to the mysql query log. Any ideas why this happens?

[Dovecot] Dovecot is emptying Maildir folders
by Alexander Johannes 20 May '09

20 May '09

Hello, i have a annoying problem with dovecot after updating to 1.1.14. Dovecot seems to empty all cur/ and new/ Folders in the Maildir of a particular user several times a day (3 times so far). It leaves only unread messages in their place. All Index-Files are getting updated and reflect the "empty"-State of the Mailbox. A quick look over the logfiles reveals nothing which seems to be relevant to this malfunction. The error_log is empty for the relevant timeframe. There is no Expire/Expunge-Plugin running. Fortunately i have a hourly backup-snapshot to restore the Mailboxes, but this is obviously no solution. How can i debug this problem? Any advice is welcome. System: FreeBSD 7.1-RELEASE, dovecot-1.1.14, dovecot-managesieve-0.10.6, dovecot-sieve-1.1.6 (all installed via the ports-tree), exim-4.69_3 Clients: Thunderbird, Mail.app both IMAP only Regards, Alex

[Dovecot] using postfix+dovecot+squirrell+amavisd and spam folder per user
by ESGLinux 20 May '09

20 May '09

Hi All, As I say in the subject I use postfix, dovecot with squirrellmail as webmail and amavisd as spam control, My problem is that all the spam I catch is send to /var/lib/amavis/virus but I want to send this mails to the spam folder of each user. This way the user can see the mails and determine if they are really spam or false positive. I dont know exactly what element of the system is the responsible to do that (dovecot, amavis, posttix) any suggest? (although only be the initial point to look for it) Thanks in advance ESG

Hi! I'm using Dovecot 1.1.15 on OpenBSD 4.4.

How does imap server should handle search requests with non latin symbols? Rightnow thunderbird 2.0.0.21 and dovecot1.2rc3 are unable to find any message if I try to search for cyrillic symbols. fts, and squat plugins are enabled

Running Dovecot 1.1.8. Have several email accounts with thousands of messages in them that are left on server. Is there anyway to speed up POP3 access without switching to IMAP? Doubt it but thought I would ask. Matt

[Dovecot] pop3 gives a permission denied error on chdir
by Kenneth Gonsalves 19 May '09

19 May '09

hi, I am running debian lenny standard install and dovecot also as a standard install. I have a problem with POP3 access. The error message is: May 19 09:16:10 greenchilly dovecot: chdir(/home/vmail/example.com/john) failed with uid 5000: Permission denied May 19 09:16:10 greenchilly dovecot: child 26253 (pop3) returned error 89 May 19 09:16:10 greenchilly dovecot: pop3-login: Login: user=<john(a)example.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured I have looked at the archives and see that the problem has been reported before, but cannot find any solution. Dovecot as LDA has no problem accessing and writing mails to the directory as UID 5000. I suspect that it is trying to access some other directory and the error message is misleading. The directory /home/vmail/example.com/john is owned by user vmail with UID 5000. Any clues? my config: greenchilly:/etc/dovecot# dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login mail_privileged_group: mail mail_location: maildir:/home/vmail/%d/%n/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: plain login passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: static args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail -- regards Kenneth Gonsalves Associate NRC-FOSS http://nrcfosshelpline.in/web/
