Re: Need to build a new mail server



As a sysadmin at a medium mailhosting ISP (~15,000 email customers,
averaging about 5 email addresses per customer,) we use a load balanced
cluster of Dovecot and exim servers with mysql backend.
Theres no way we could use qmail, it just doesnt have the flexibility
even with 1/2 a dozen patches.
That said I do like postfix I've used it before for smtp relay servers
and its performed like a champ.

my take running an ISP based mail system
Postfix Definately
Qmail, its ok, in most cases scenerios
Exim - No way

and Dovecot or Cyrus for imaps/imap

I also recommend dovecot. I'm using it for several years
without a problem, and it was quite simple to setup.

I'm using it with sendmail, though (not postfix), because
I've been using sendmail for almost 20 years and haven't
had a reason to switch. If you're already familiar with
sendmail on Solaris, then I recommend you continue using
sendmail on FreeBSD (it's the default MTA that comes with
the base system).

Having said that, Postfix _is_ a very good MTA, I'm using
it at work. If you're willing to switch and invest a
little bit of time learning something new, then Postfix
is certainly a good choice. It's quite easy to install
Postfix from the ports collection.

Best regards
Oliver
