Just out of curiosity, what would people recommend for large scale email? (what distro and application) I'm not wanting to start a flame war, just get opinions from people in that have had more experience than I have in large scale email. That said, here are the factors for consideration:
- I am migrating email from a Win32 environment to a *nix based
environment. :) I am working with people that I have to remind that Linux is not a singular all-encompassing distro (ie: that Linux does means Linux but rather SuSe, Redhat, Mandrake etc..) 2) It must be ultra-secure. 3) Large scale means over 1,500 mail boxes and approx 350 to 400 domains.

I am partial to Postfix/Cyrus/MySQL/Amavisd/Clamd/SpamAssassin/squirrelmail. We wrote a custom front end for maintaining the user base. Cyrus is extremely fast and efficient, though not always the easiest to configure. Once configured though, it just works and works well. I started with Luc Delouw's how-to. I did find though that some significant hacks were needed to make the setup truly capable of handling virtual domains. As I mentioned, we are not using the web-cyradm front-end, but you should be able to. I am actually using Procmail to filter out the domains and this is not recommended by Procmail, but I have not seen any problems with it. The filtering is good and solid and Squirrelmail has a ton of plugins, many of which allow userinfo including spam filtering preferences and black/white lists to be stored in MySQL. This setup takes a bit of time to get up and running, but IMHO is a feature-rich, rock-solid high performance system.
I have this running on RH8, RH9, and Fedora Core2.
