/usr/local/bin/tcpserver -c 550 -x /etc/security/tcprules/inbound.cdb \
-u qmaild -g nofiles 0 smtp /var/qmail/bin/qmail-smtpd &
with aforementioned line present in the inrules file compiled to
create inbound.cdb did let it through. i don't know why.
qmail-smtp is modified to print out the IP of the sender. that was
209.244.137.13. Level3 communications eliminated the user
connected to that IP. That is when he went away. The mail
flowed until then. My servers were bogged down to prove it.
Everything works w/ tcpserver for every other situation except
for this character yesterday and I believe the same guy a few
weeks back.
