Large imap server.

Specifically my mail server combo was:
FreeBSD 4.1 + Qmail + Courier IMAP + MySQL 3.22

Qmail handles all incoming mails. With a simple Perl script using
Mail::Audit, incoming mails are dropped to whatever directory is specified
by a lookup on the MySQL table. Courier IMAP uses the same table to respond
to IMAP connections. Since Maildir is used, we have experienced 0 mail
corruptions since we moved away from Sendmail.

Hope this helps.
