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.
