[Dovecot] default mail quota when using per user quota
by Andreas Helmcke 14 May '12

14 May '12

Hello, using dovecot 2.1 and per user mail quota via ldap is there a way to have a default quota which gets used, if the "quota" field in ldap is not set? I tried with: plugin { quota = maildir:User quota quota_rule = *:storage=3G } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } and in dovecot-ldap.conf: user_attrs = dcMailQuota=quota_rule=*:storage=%$ but with this configuration the mail quota /allways/ gets loaded from ldap resulting in users without dcMailQuota attribute having no quota at all. Greetings Andreas

[Dovecot] doveadm not working
by Christian Rößner 14 May '12

14 May '12

Hi, I know I must have done some misconfiguration, but I do not know where to start searching for. All began when looking at my weekly cron message, where doveadm purge -A is run. That fails. So I tried doveadm quota -A as well, which several weeks ago was working perfectly. Example: doveadm quota get -A doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Username Quota name Type Value Limit % All I see in the logs is: May 13 13:03:20 mx0 dovecot: auth: Error: auth worker: Aborted request: Lookup timed out May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Connect error May 13 13:03:21 mx0 dovecot: auth-worker(26753): Error: LDAP: ldap_start_tls_s() failed: Can't contact LDAP server Dovecot itself works. Only doveadm does not. My LDAP is using SASL/EXTERNAL. Certs are in standard folders under /etc/ssl/{certs,private} (see below). I guess that "some" user (but which?) tries to read the certs but is disallowed. Can somebody help me please to fix my permissions on that (private used) mail server? Is my "vmail" user required?

[Dovecot] Log files
by Chris Lasater 14 May '12

14 May '12

Hi, I just started using Dovecot and was trying to create separate logs instead of using syslog. Is there a way to get the file permission to be something other then root? I have tried the below configuration and it does not seem to change anything. The log process does change to a new user, but it still creates and writes as root. Whenever I test a new setting I delete all the current logs so they will have to be recreated to make sure it does not just keep the previous permissions. I also dont see much documentation on the service log. according to dovecot -a there are a good number of options, but I dont see any information about them. Here are my logging settings below and I am running 2.1.6 and tried on 2.1.5. ### Logging info_log_path = /home/user/dovecot/logs/dovecot_info.log log_path = /home/user/dovecot/logs/dovecot.log debug_log_path = /home/user/dovecot/logs/debug.log service log { user = user unix_listener log-errors { group = user2 mode = 0620 user = user } } Thanks, Chris

[Dovecot] dovecot report W value error and Corrupted index cache file
by 甄东宇 14 May '12

Hello everybody, I have a problem and no idea. Yesterday Dovecot.log report: Warning: Fixed a duplicate: /opt/*/cur/<time>.M*.<domain>,S=*,W=*:2,S -> <time>.M*.<domain> Now Dovecot.log report: Error: FETCH [ ] for mailbox INBOX UID 10546 got too little data: 79850 vs 81231 Error: Maildir filename has wrong W value: /opt/DIR/DOMAIN/USER/cur/1281317869.M*.*,S=79569,W=81231:2,S~ Error: Corrupted index cache file /opt/DIR/DOMAIN/USER/dovecot.index.cache: Broken virtual size for mail UID 10546 A few days ago, we used a new machine for mail server (and we used maildir format with dovecot-1.2.0).In fact ,we used iRedmail on CentOS5. And last week, I copy some mail data from old machine to new one through SCP and CP command. It worked well. Yesterday, I copy the mail data from old machine to new one through RSYNC. I guess maybe the errors have a relationship with rsync, because the new machine open SELinux and the rsync data error. Although the files were copyed to /cur directory , it seemed to appear the same mail file. Now,I receive some BLANK mails by pop3 of OutLook2007 . There are not any Header and any Body( Totally BLANK). Outlook show they are 760B size. I am confusing for this problem. Please help me. Thank you.
