I think dovecot simply ignored this. I wonder if the alias quota_rule makes any sence to Dovecot as I only see : quota = dict:user::proxy::quotadict defined in the dovecot.conf and not quota_rule. # cat /etc/dovecot/dovecot-sql.conf password_query = SELECT username as user, password FROM mailbox WHERE email='%u'; user_query = SELECT 5000 AS uid, 5000 AS gid,'/home/vmail/%d/%n' as home, concat('*:storage= ', quota) AS quota_rule FROM mailbox WHERE user = '%n';

[Dovecot] BUG:v2.0.9 + expire plugin segfault
by Nikita Koshikov 17 Jan '11

17 Jan '11

Hello list, New version of dovecot segfaulting with expire plugin(sqlite db). Steps to reproduce: 1)DB file has permitions: -rw-r--r-- 1 mail mail 87040 Янв 17 10:04 /var/mail/expire.db 2)Dict dovecot config section: service dict { # If dict proxy is used, mail processes should have access to its socket. # For example: mode=0660, group=vmail and global mail_access_groups=vmail unix_listener dict { mode = 0600 user = mail } #user = mail } 3)Trying to add new record to database I get: Jan 17 10:03:12 dict: Error: sqlite: exec(INSERT INTO expires (expire_stamp,username,mailbox) VALUES ('1294852805','user(a)domain.com','Trash')) fail ed: attempt to write a readonly database (8) Jan 17 10:03:12 IMAP(user(a)domain.com 192.168.2.252): Error: read(/var/run/dovecot/dict) failed: Remote disconnected Jan 17 10:03:12 master: Error: service(dict): child 13957 killed with signal 11 (core not dumped) This crash has gone after service dict got enough permission to access db file(user mail in my case). Don't know how to get backtrace with dict service, but can reproduce crash any time.

[Dovecot] vpopmail disabled services fix
by Calvin 17 Jan '11

17 Jan '11

I noticed that disabling services using vpopmail was not being recognized by dovecot. Using "vmoduser -swip user(a)domain.com" should disable all services, but both pop and imap logins were still allowed. After a bit of digging in the code and confirming with a few debug lines, it appears that lines 38 and 52 of src/auth/passdb-vpopmail.c are the issue (dovecot 2.0.8). These two lines do a strcmp on request->service. It appears that request->service is in lower case, but the comparison values are in upper case. Either updating the values to lowercase or using strcasecmp should fix the issue.

[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis
