[Mimedefang] Re: OT: Anyone here use Dovecot imap server in production evironment?

[Atanas]

I'm using courier-imap quite happily for about 2 years on dozens of 
boxes with 2-3K users/virtual domains and 5-10K email accounts per box. 
These are primarily web servers, and for only a small fraction of the 
resources a single installation of courier-imap handles about 200-500K 
pop3/imap logins a day.

It's well thought, flexible and efficient. You can attach it to whatever 
LDA you like, for instance I'm using it with procmail, and have also 
another setup with maildrop. You can use whatever authentication you 
like - PAM, userdb, mysql, LDAP, etc.

Besides the courier-imap and maildrop, the courier project also has 
another somewhat mature and useful child - sqwebmail. It's a basic 
CGI-based webmail client, which is very fast (works directly with the 
maildirs). So accessing large folders with imap, pop3 or webmail is not 
a problem.

It's not that much of a rocket science to configure it, especyally when 
you have it almost preconfigured in FreeBSD ports. I can post some 
sample configuration hookups if someone is interested.
