The only one commonly voiced is that some spamware doesn't understand
a DENY on connect, and will enter a tight retry loop, using up your
resources and filling up your logs. Most common practice is to do all
the DENYing at RCPT time - you get the added benefit of more
information about the proposed transaction at that point, too.
