OK, here's where my ignorance starts to show. Where is this information
logged? If its in /var/log/qmail/qmail-send/current - I'm seeing 1/20 or
2/20 at most. Those numbers aren't growing, but I can't find log info for
tcpserver. I am seeing zippo related in /var/log/messages

More ignorance - advice taken.

See above (i.e. which log?). Its mainly the fact that I understand the
interaction of TCP/IP, DNS, and SMTP much better than qmail itself at the
moment.
Thanx again,
