Some possible tutorials to help you on your way are: QMR (qmail rocks) FreeBSD http://freebsd.qmailrocks.org/ ( Has Mysql, vpopmail, clam-av, spamassin, ) Mail Toaster http://www.tnpi.biz/internet/mail/toaster/index.shtml (has mysql) An honest 50,000 users an mysql implementation might be a little more hardware intensive then an ldap in the long run so you might want to drop a mail to freebsd-isp mailing list and ask around there too for ldap stuff. Dont forget to if you plan on using maildir as a mail storage solution then remember that inodes become very important because you WILL run out of them. A solution can be found in the existing man pages, read "man tuning" before proceeding onto building your server. You might want to stay away from old school imap software like imap-uw because they lack the advanced features like quota support that you will need to enforce quotas for your users.
