[Dovecot] migrating from Courier
by LuKreme 23 Nov '09

23 Nov '09

I've been running postfix/courier-ssl/MySQL/postfixadmin for years, but since I am in the process of building a new server I decide to reexamine my options. I'm sticking with postfix, but I've decided to move from courier to dovecot because everyone is telling me it's much faster, and I really dislike courier's SASL setup and integration with other services. Of course, I have dozens (but not hundreds) of gigabytes of Courier Maildirs for all the users. Most of the users are in MySQL virtual domains and their mail is stored in a common directory (/usr/local/virtual) and owned by a single system user (vpopmail). I've even hacked together a postfix service to run procmail for the virtual users, though my intention of creating a webface allowing them to muck up their own .procmailrcs never came to fruition. I'm doing my user migration in two steps. First, I will rsync all the mail (and all the user webfiles) to the new server, do any setup/conversion/&c to the data on the new server and make sure everything is working and that passwords are preserved. Then, right before the server goes live I will shutdown mail on the old machine, rsync any new mail (hopefully no more than a couple of hours worth) over, do any conversion, and then fire up the new server. 1) what do I need to do to convert or prepare the courier maildirs for dovecot? 2) is the current setup of virtual users reasonable for dovecot? 2.1) Is there a better option than postfixadmin? 3) some of my users are not in MySQL, but are real system users. Is this going to confuse dovecot (it confuses courier no end). These system users are still using courier and courier maildirs. 4) would it be better to take the server live and THEN move/convert the old mail? 5) anything else obvious that I didn't mention or ask that I should have? The most important thing, of course, is to not lose anyone's email. -- "Two years from now, spam will be solved," -- Bill Gates, January, 2004

[Dovecot] Dovecot and SATA Backend
by Nicolas GRENECHE 23 Nov '09

23 Nov '09

Hi all, I plan to run a dovecot IMAPS and POPS service on our network. We handle about 3 000 mailboxes. I thought first buying a topnotch server (8 cores and 16 Go RAM) with equalogic iSCSI SAN SAS 15K for storage backend. On second though (and after a comprhensive read of dovecot features), I saw in http://wiki.dovecot.org/MailLocation that index files can be created on a separete local filesystem. My question is : for 3000 users, is it possible to have only a SATA backend attached to my topnotch server (to handle bigger mail quotas) by storing index on local hard drives (SAS drives) ? Extra question, what is the better : iSCSI SATA backend or NFS share ? NFS share is more convenient to have a failover server. Thanks for your help.

hi all, i hope it´s okay for questions about the sieve plugin here... my problem is, that the filters do not seem to match utf8-content for instance: the email: Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Subject: =?utf-8?Q?Erinnerung:=20Bitte=20f=C3=BChren=20Sie=20die=20Kaufabwicklung=20durch?= when i use the same subject (of course in utf-8) in my ".dovecot.sieve", the filter never matches ;-(( does anyone have an idea howto make the sample here matching by sieve ??? thank´s for any help! michael

[Dovecot] kudos
by Frank Cusack 21 Nov '09

21 Nov '09

I'm sure this isn't said enough, so kudos to Timo for what has to be the best IMAP server anywhere, hands-down no qualifications! And to think, it's a one man operation ... although perhaps that is one of the reasons it is so good.

[Dovecot] Problem compiling dovecot 1.2.8 on Solaris 10?
by Drew Schatt 21 Nov '09

21 Nov '09

I've got an issue using Sun's compilers on Solaris 10 - it appears that dovecot is trying to use the getopt function, that's part of GNU's glibc, and, therefore, not present when using Sun's compilers.

[Dovecot] Plugin Compatibility
by Tony Rutherford 20 Nov '09

20 Nov '09

We are looking to develop a plugin against the 1.2.X line (8 as of right now). Seeing that v2.0 is not too far off, is there any reason to think that a plugin developed for 1.2.X would NOT be compatible with the 2.0 line?Thanks,Tony This message is intended solely for the individual(s) to whom it is addressed.
