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 After realizing that the HOWTO was out-of-date (damn!)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.
