mail server recommendations?

[Aristedes Maniatis]

We have sold Communigate Pro (http://www.ish.com.au/communigate) to 
customers with up to 30,000 accounts. Others run up to 100,000 on a 
single server, more in a cluster. It runs great on FreeBSD and that is 
the combination we usually recommend and use ourselves. It costs money, 
but you didn't say whether you wanted a free or commercial product. You 
also don't mention how many accounts you need to run, as that has a big 
bearing on the cost of a commercial offering compared to putting 
together the elements you need yourself (webmail, IMAP, SMTP, SSL, 
MAPI, etc).

You can download a fully working version of the product for trial 
purposes.

Cheers
