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.
