Desc: - Improved the POP3 error message if an account was suspended or (and now) temporarily locked to indicate such. - SMTP receiver. Suspending users (NAUTRY) for failing a password check ended up being too disruptive as spammers are just too relentless, so now have an option (LOCKTYPE) to instead lock the account for a few minutes. This should have a spammer give up when they start getting denied messages and the user is less effected.
