Add TARPIT patch by Chris Johnson <dcj-qmaildoc@palomine.net>
What's tarpitting? It's the practice of inserting a small sleep in an SMTP
session for each RCPT TO after some set number of RCPT TOs. The idea is to
thwart spammers who would hand your SMTP server a single message with a long
list of RCPT TOs. If a spammer were to attempt to use your server to relay a
message with, say, 10,000 recipients, and you inserted a five-second delay for
each recipient after the fiftieth, the spammer would be "tarpitted" and would
likely assume that his connection had stalled and give up.
