Question Migrating from Postfix/Courier to Exim/Dovecot

Hi Everyone,

I have a Debian Lenny 5.05r with Postfix 2.5.5 and ISPConfig 3.0.3 installation. And due to performance issues on the vserver, postfix is not running as good as it should do (Postfix needs more & more sockets, http://www.howtoforge.com/forums/showthread.php?t=48002). So I asked at several places on the Web, and got the answer that Exim is more lightweight as Postfix, and may be the right choice in my case. On the other hand, I'd like not to start a new installation from scratch, but rather to migrate the mailboxes and the hole mail-data from Courier to Dovecot, and also to configure ISPConfig3 to continue setting up virtual domains / mailboxes etc. as good as it did with Postfix.
I found here this old thread "http://www.howtoforge.com/forums/sho...highlight=exim", which is I think outdated or maybe could not conform to my actual environment.
I'm very thankful if any one could give me some good hints.

Wahid

ISPConfig 3 doesn't support Exim, and I don't know if it can be changed to do so. Would be a lot of work in any case...

Question RE:Migrating from Postfix/Courier to Exim/Dovecot

Hi Falko,

I Know that ISPConfig doesn't officialy support Exim MTA, and I also would like not to spend a lot of time on tweaking/re-configuring the webapplication to integrate finally Exim in a wrong way. That's why I'm looking for alternatives to solve this, so feel free to post your suggestions !

Aside from ISPConfig, when I install Exim/Dovecot, will it be possible to "import" the content of Courier IMAP Maildirs into Dovecot ones or something in this sense?

Looking forward to hearing your suggestions !

I don't have any suggestions, aside from running Postfix instead of Exim.

As both use Maildir, that should be no problem. (You might have to rename or delete a few folders inside Maildir, if you see stuff in your IMAP client that doesn't make sense.)
