Yes, it seems to be necessary. I have already come across the situation
where pop3d refused to update user's mailbox after arrival of
some new mail during the session. I am going to implement this.
By the way, by this time pop3d is running 2 days under a rather
heavy load, the only problem I have seen so far is that of grown
mailboxes.
