[Dovecot] Populating mailbox dir
by Mauricio Tavares 20 Jan '11

20 Jan '11

Let's say you created a (virtual) mail user but have not created the user mail directory. When you first try to access it, the mail directory is created and populated: ls -a /var/spool/vmail/domain.com/raub/ . dovecot.index.log dovecot-uidvalidity.4d375a39 tmp .. dovecot-uidlist new .Trash cur dovecot-uidvalidity subscriptions Who populates/creates the initial files and folders in the user mailbox? Dovecot? The mail client accessing it through imap? Elvis? If dovecot, is there a way to customize it a bit, so a few extra folders will also be thrown there?

[Dovecot] domain stripping
by PA 20 Jan '11

20 Jan '11

Hi, using dovecot 2.0 and I'm using a couple of user DBs, sql/prefetch and pam. Currently if the user logins with username@domain it authenticates off the sql DB and works fine. If the user logins with username with no @domain it fails on the sql lookup and succeeds on the pam user DB. However I was wondering if I can have another sql DB lookup that says when the user logins and fails against the first two user DBs, sql/pam db, to try this last sql user DB and appends a default domain to it, because the sql DB lists username with the domain. Currently I have all users login in with no realm on the older mail server and I wanted to migrate these users to dovecot 2.x with minimal impact and wanted to have the ability for these virtual users to login with and without a realm. Thanks paul.

[Dovecot] Bug found, assertion failed
by Tobias Daucher 20 Jan '11

20 Jan '11

Hi there, We're running dovecot 2.06, with mdbox. Following message was in our syslog: Jan 20 09:26:48 servername dovecot: [ID 583609 mail.crit] imap(user): Panic: file istream-limit.c: line 79: assertion failed: (v_offset <= lstream->v_size) The problem could be solved on client side, by just deleting the ImapMail-Folder in Thunderbird. Why? Thunderbird tried to move a message, that obviously wasn't there. Dovecot got killed and the message above was in the syslog. Connection was closed and Thunderbird told me the server is dead. Thunderbird tried this every few seconds, and there was no way to say thunderbird "stop try moving". So the only way was to delete thunderbirds mail cache. I think it would be very nice, if dovecot doesn't die, just because the client tries to move a message, which isn't there.

Go with a cluster filesystem such as OCFS or GFS2 and an inexpensive SAN > storage unit that supports mixed SSD and spinning storage such as the Nexsan > SATABoy with 2GB cache: http://www.nexsan.com/sataboy.php I can't speak for OCFS2, but after several years' experience with the filesystem I strongly recommend NOT using GFS/GFS2. Its locking model is incredibly slow (500 locks/second on a filesystem mounted with quotas enabled and noatime) and results in dire performance - plus there's a known crash vulnerability if files are repeatedly renamed in large directories (this bites us regularly...) GFS2 isn't an "enterprise" filesystem by any stretch of the imagination, despite what a number of enthusiastic salespeople might try to convince you of. We're lucky to keep the GFS servers up for more than a week at a time.

[Dovecot] Upgrading from 1.2 to 2.0
by list＠airstreamcomm.net 20 Jan '11

20 Jan '11

Greetings Dovecot mailing list! We are an ISP that recently migrated from Courier to Dovecot, and are looking at the next round of upgrades. Hoping that we could get pointed to some documentation or get a general list of best practices for an upgrade from 1.2.13 to 2.0.9. Our current environment consists of four Dovecot machines that share an NFS backend hosting POP and IMAP. Our biggest question is whether we can support a rolling upgrade from 1.2.13 to 2.0.9, or if it would need to be an all for one cut. Thanks in advance.

Cool, thank you Patrick! Must have missed that somehow. I put the setting in main.cf, "receive_override_options = no_address_mappings", right after 'content_filter' (running amavisd on a separate port) and it seems to have fixed the problem. -- Darek On Tue, Jan 18, 2011 at 7:05 PM, Patrick Westenberg <pw(a)wk-serv.de> wrote: > Darek M schrieb: > >> Anyone have an idea of what I should be looking at in a situation like >> this?
