As promised earlier, now Dovecot 1.2.0 is released, I’m officialy launching the new mailserver setup with Postfix and Dovecot (Currently Leopard only).

This means no more Courier based products like the authentication, IMAP, POP3 and maildrop apps. Dovecto can do all that with a single installation. I’ve found out that the setup is a lot simpler with a lot fewer procedures and configuration files to maintain.

An last but not in the least, it looks like Dovecot is proving to be an even better IMAP server than Courier was. As I told you in the earlier post it’s a lot faster. While testing it myself I often saw new email appear in Mail or Thunderbird immidiate after thy were received by Dovecot.

Currently the setup only describes the basic setup of a server, I still need to add the DSpam spam-filter in the setup and integrate server based filtering of incoming emails (where we used to use maildrop for). It is all possible but I still need to find out how and document it for you. When that is done I will write the neccesary migration documents how existing users can migrate safely from Courier to Dovecot.

I will keep supporting the Courier product stack for at least a year after I finished documenting the migration instructions. So don’t worry if you don’t switch immediatly. My production servers still run Courier, I only use Dovecot on my test servers. Although there is one user who has already switched to Dovecot (We helped each other in getting this done) because of the performance problems he experienced with Courier IMAP. These problems are now gone and this is one of the reasons I want to move to Dovecot a.s.a.p.

The advise currently is if you want to setup a new server: Use the Dovecot based setup. If you already use Courier please wait untill the migration instructions are finished. If you can’t wait I will try to assist you via email as much as I can but you will be mostly on your own. It’s not that difficult but ou need to know what you are doing.

I hope you like the switch and will be happy with the improved setup. You can read all about it at the new mailserver instruction pages
