The following configuration is used for few hundreds users, with:
20 Mb message size limit
5000 files per message limit
5000 messages sent/day
7000 messages received/day
The user database is shared with other applications.
smtp : postfix + pop-before-smtp
pop3, imap : courier
antivirus : amavisd + clamd + H+BEDV AntiVir
(twice scanned because we had unrecognized virus in
the past)
database : mysql
webmail : horde/imp + php + imap (other server)
antispam : -none-
the iron under is amd64 dual opteron, used for _other_ heavy tasks
To port the user from whatever mail daemon the most simply road is
export them in a text file, then translate it to sql (INSERT INTO ...).
IMHO the best MTA avaiable in opensource world are Postfix and Qmail,
always IMHO the opensource MTA are better than the commercial alternatives.
