[Dovecot] Renaming user account / mailbox
by Nikolaos Milas 02 Feb '12

02 Feb '12

Hello, I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7. All accounts are virtual, hosted on LDAP Server. We are using Maildir mailboxes. The question: What is the process to rename an existing account/mailbox? I would like to rename userx with email: userx(a)example.com to ux(a)example.com with a mailbox of ux (currently: userx) Of course the idea is that new mail will continue to be delivered to the same mailbox, although it has been renamed. How can I achieve it? Would it be enough (after changing the associated data in the associated LDAP entry) to simply rename the virtual user directory name, e.g. from /home/vmail/userx to /home/vmail/ux ? Thanks in advance, Nick

[Dovecot] Site-wide configurable Sieve
by Gedalya 01 Feb '12

01 Feb '12

Hi, I need some sieve actions to be specified per-user, but exposing actual sieve scripts to users is of the question. For example, I need to be able to either put spam messages into a spam folder, or discard them, based on user preference. Presumably this would be done using Sieve. As I understand, it's not possible to query a database from within a sieve script. If I can't use a single global script, I can imagine automatically generating per-user scripts when settings are saved in a GUI (e.g. webmail) and store them on the dovecot machine. This would work but I would love to hear if someone has a smarter, more robust idea. Thanks, Gedalya

[Dovecot] LMTP : Can't handle mixed proxy/non-proxy destinations
by Alexis Lelion 01 Feb '12

01 Feb '12

Hello, In my current setup, I uses two mailservers to handle the users connections, and my emails are stored on a distant server using NFS (maildir architecture) Dovecot is both my IMAP server and the delivery agent (LMTP via postfix) To avoid indexing issues related to NFS, proxying is enabled both on IMAP and LMTP. But when a mail is sent to users that are shared between the servers, I got the subject mentionned error in the logs : Jan 25 09:05:12 mail01 postfix/lmtp[23934]: A92709300DB: to=< user_on_mail02(a)domain.com>, relay=mail01.domain.com[private/dovecot-lmtp], delay=0.07, delays=0.01/0/0/0.06, dsn=4.3.0, status=deferred (host mail01.domain.com[private/dovecot-lmtp] said: 451 4.3.0 < user_on_mail02(a)domain.com> Can't handle mixed proxy/non-proxy destinations (in reply to RCPT TO command)) >From what I saw, the mail is then put in the queue, and wait until the next time Postifx will browse the queue. The mail will then be correctly delivered on "mail02". However, the "queue_run_delay" postfix parameter is set to 900, which means that the mail will be delivered with a lag of 15 minutes. I was wondering if there was another way of handling this, for example by triggering an immediate queue lookup from postfix or forwarding a copy of the mail to the other server. Note that the postfix "queue_run_delay" was increased to 15min on purpose, so I cannot change that. I'm using dovecot 2.0.15 on Debian Squeeze, kernel 2.6.32-5-amd64. Thanks, Alexis

[Dovecot] Issues w/ Apple devices after migration to dovecot
by Armistead, Kurt 01 Feb '12

01 Feb '12

Hi guys. Recently we've moved our old (and I mean _really_ old) mailserver to a new hardware. Since I had quite some time on my hands, I decided to switch from courier to dovecot. Transition went pretty smoothly and the users experienced just a few hours' blackout. Only trouble now is that, after re-configuring some IOS handsets and tablets, not all messages are displayed correctly. For example, I had a long existing mailbox (roughly 1600 emails in INBOX and about a dozen other folders) that showed up perfectly on my iphone. Now it's been synced to the new dovecot server via imap and a whole month of messages seems to be missing. I checked on the server, via webmail and with outlook and everything is where it should be. The problem shows up on Apple devices (same thing happened on a couple of ipads). I haven't tried rebuilding the index or wiping out a phone to see if that resolves the problem, but before I do that I'd like to know if anyone experienced the same issue and how they fixed it Thanks! Kurt

[Dovecot] Uncompressing dboxes
by Lauri Alanko 01 Feb '12

01 Feb '12

Hello. I have an mdbox directory that has been created with the zlib plugin active, using bzip2 compression. I would now like to convert these into uncompressed mdbox format. How do I do this? I have tried unsetting all zlib-related configuration options, but dsync still produces compressed mdbox at the other end, too. I guess I could convert to mbox, and then back to mdbox, but for certain reasons I'm not very enthusiastic about doing anything mbox-related with dovecot any more. (Incidentally, it's a bit funny that when the zlib plugin is enabled, dsync automatically creates compressed dboxes, and even compressed maildirs (which is pretty useless), but not compressed mboxes, although that's where compression would be most beneficial.) Thanks, Lauri

[Dovecot] Temporary forbid some users login ?
by Frank Bonnet 01 Feb '12

hello is there a way to forbid SOME ( not all ) users's login with dovecot 2 ? I need to move their IMAP folders to another place with more disk space but I don't want to stop dovecot IMAP service for the other users as the moving process will be a bit long ( 1 Tb to move ) thanks
