[Dovecot] Maildir and Solaris UFS acls
by Tom Lieuallen 21 Dec '10

21 Dec '10

I have a centrally located shared imap folder location. We have several maildir folders with different file system permissions. They are for several groups of people who are loosely related for support purposes. All mail gets delivered to queue1 just fine. The files are group writable by group1. Some of the mail gets moved via imap to queue2. Queue2's maildir tree is configured with Solaris UFS acls such that any new files are read/write by group1 or group2. If a new file is created within queue2 anywhere, it has the correct permissions. However, if a message is moved from queue1 to queue2, it retains the permissions that it had within queue1. This is what happens if I use 'mv' within the file system, btw. Is there any way to configure dovecot such that if a person moves or copies a message to another imap folder, it creates a new file instead of doing a link or mv or whatever? If not, no problem; I was just hoping for an elegant solution to my particular problem. :-) queue1 - read/write by group1 queue2 - read/write by group1 & group2 through solaris ACLs BTW, if any file whatsoever in queue2 is not readable by group2, those in group2 cannot read _anything_ in queue2. thanks Tom Lieuallen

[Dovecot] quota issues
by PA 20 Dec '10

20 Dec '10

Hi I seem to be getting an error when quotas are enabled. Also I noticed that the quota_ rule settings don't actually get used, the only settings that are used are on the sql.conf file. Maybe I'm not understanding what the quota_rule does but should I be specifying the storage/messages values on there even though they are being read/used are on the sql.conf file only. dict { quotadict = mysql:/usr/local/etc/dovecot/dovecot-dict-quota-sql.conf } plugin { quota = dict:::proxy::quotadict quota_rule = *:storage=1M:messages=5 quota_exceeded_message = Quota exceed, please email support for further assistance. trash = /usr/local/etc/dovecot/trash.conf.ext driver = sql } Sql.conf user_query = SELECT concat('/var/vmail/%d/', maildir) as home, concat('maildir:/var/vmail/%d/', maildir) as mail, 101 AS uid, 502 AS gid, concat('*:messages=5:storage=', quota) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1' Below are the errors I'm seeing in the log.

[Dovecot] Sieve create non-existent folder

Hello, Is there a way to have a Sieve script create a non-existent folder rather than have it deliver messages to INBOX instead? I'm using Dovecot 2.0.8 with Postfix, via LMTP. Thanks!

[Dovecot] Best way to move mail to an archive
by Richard C. Cox 19 Dec '10

19 Dec '10

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory. Ideally, I would like to set up a cron job to search for e-mail in all of my imap directories that older that 'X' days and move it to the archive directory. I know that dovecot wants to manage e-mail movement thru the IMAP interface, so I'm leery of just using ordinary Linux commands to move mail around and bypass the IMAP protocol. Does anybody have any recommendations about dovecot/IMAP safe commands I could use to accomplish this task? Thanks in advance and I apologize for not being more knowledgeable about this subject. Regards, Richard

[Dovecot] Problem with expunge
by Jeff Mitchell 18 Dec '10

18 Dec '10

I'm running Dovecot 2.0.8. The other day I tested doveadm expunge on a test Inbox with a few messages received over the course of a day, and using savedbefore <a few hours>, and it seemed to work. However, today I was testing converting some maildirs over to sdbox, and noticed odd behavior: it's deleting all messages in the specified folder instead of just the ones matching the condition I'm using ("savedbefore 4w"). The command I'm using is "doveadm -Dv expunge -A mailbox Trash savedbefore 4w" Because of the conversion, all of the ctimes for all of the files are actually the same (basically, a few minutes ago), due to the converstion to sdbox from maildir, so I would expect that either it doesn't delete any of them or looks inside at some header of the mail (half of which was received/placed into Trash before 4w ago and half of which wasn't). I definitely don't expect full-on deletion... Any idea what's going on? Thanks, Jeff
