Bull's eye!   That's what I was looking for.  Did anybody tried it
today?  It look like thay have problems on their side because all it
says is:

/proj/maps/bin/in.relaytest: socket failed [bad file descriptor]
connecting to  (the right IP address I use..)
connection to host failed

There was not a single attempt logged on the mail server.
