Cyrus or Courier?

[Haim Dimermanas <dudle@linuxroot.org>]

Hello fellow Debian users,

 I am in the process of setting up an email system that will host
thousands of domains, many aliases per domain as well as forwarding
capabilities on a per-domain basis.

 As far as the MTA is concerned, my choice is postfix. After reading the
postfix-users mailing for a week (~60 msg a day), I think I got a good
feeling about how postfix works.

 I am now confronted with choosing a good Local Delivery Agent. I heard
great things about Cyrus so I gave it a shot. After realizing that the
HOWTO was out-of-date (damn!) and that the Cyrus documentation was
somewhat cryptic, I am now considering Courier.

 What I need is something that is scalable, reliable and working with a
database (MySQL first, maybe Oracle later on). Between Cyrus and
Courier, which one do you recommend? Please note that I am not trying to
start a flame war, I just need to make an important decision.

 Thanks.

	Haim.
