Postfix handles SMTP, not IMAP/POP3.  I use dovecot for IMAP/POP3, but
I'm more interested on security than performance, so..... maybe
someone else can suggest a faster IMAP server (although dovecot is not
slow, I think, just for the record).  Also, the format of the
Mailboxes *is* important, and, off course, you need some kind of
*shared* storage, or storage replication (not sure here), and either
of these have to be fast.

500Mbytes (ie, ~5Gbps) or 500Mbits (500Mbps).  Also, is the traffic an
addition of SMTP + IMAP/POP3 traffic, or just IMAP/POP3 traffic.
