I would highly recommend looking at Dovecot.  I have used courier for
several ISPs then switched to Dovecot on my last install.  Its ability for
caching the index per user is of great performance advantage if you choose
to leverage an IMAP based webmail solution (like Roundcube, or even
Squirrelmail, but I would recommend Roundcube over Squrrel)...especially if
you are going to deal with mailboxes of tens of thousands of messages.
