This is pretty much what I do with the mail domain I administer. I've set the INBOX with a modest quota, and a personal mail folder with a generous quota. I encourage users to keep their INBOX as a "working set", and archive the rest using any method they prefer. It forces users to process their Email (or at least their INBOX). and keeps packratting in check. Super-big INBOX quotas seem to encourage wasteful habits. I've helped some users clean out their mailboxes and was surpised at the amount of junk being kept for years and years. Apart from a few users moaning about their meager INBOX, this policy works out fairly well. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Virtual mailboxes do not look into subfolders
by Paul Provost 17 Jan '11

17 Jan '11

Hi all, I have virtual mailboxes set up as "Smart Folders" to show me messages tagged with certain keywords. For example: # ~/Maildir-virtual/fwp/dovecot-virtual File MailingLists/* KEYWORD @fwp Messages get picked up from the File mailbox, but not for the sub-mailboxes inside the MailingLists mailbox. What am I doing wrong? Wrong separator? And how can I debug this? Everything else is working fine. Thanks a lot! Paul

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.
