Grumble! The connector's IP address ALMOST works, because ps tells us:

root 61316 0.0 0.4 3648 1940 ?? I 11:27AM 0:00.00 sendmail: server
fanta-gate.willowglen.com.sg [61.8.245.90] cmd read (sendmail)

and lsof/netstat would even give us the remote port number.

Does mimedefang-filter get the remote port number? Could I tweak the
code to pass it?

Not to disagree w/ the creator, but it seems this problem is solvable?

Saw your other email too: that's why I suggested using the grandparent
pid and not the pid of the filter itself.
