sending mail ist usual smtp ( postfix ), not dovecot
if no firewalls/proxies , slow lines , dns problems are involved, there
may exist some policy or milter service which slows down smtp out from
i.e tb, ask same question with logs and config in the postfix mail list
size of mailbox should be not involved in this
