http://hg.dovecot.org/dovecot-1.2/file/02c2ac9ddf8c/dovecot-example.conf:

   374 # Valid UID range for users, defaults to 500 and above. This is mostly
   375 # to make sure that users can't log in as daemons or other system users.
   376 # Note that denying root logins is hardcoded to dovecot binary and can't
   377 # be done even if first_valid_uid is set to 0.
