I can almost guarantee that you will see a performance increase. Also note that you don't have to change to postfix. You can configure sendmail to use whatever local delivery agent you want (ie. something like maildrop http://www.flounder.net/~mrsam/maildrop/). If it were me, I would use maildrop with sendmail first, and then replace sendmail with postfix after I have the Maildir+imap figured out. Anyway, good luck. -- Cameron Moore
