That appears to be a good fix. I duplicated the problem and I can see 
messages flowing through the the outbound queue after applying your 
change. So if this happens again at least the mail will not stop.

Thank you, very much.

Below is what I sent to the MW list describing what I found. Any 
additional input is welcomed. It's been another sysadmin kinda day, time 
to sleep.

MailScanner in debug mode shows no errors. Poking around in
it would seem like InitConnection was failing. Adding some logging
showed exactly that. So I shut down MailScanner and checked, sure enough
netstat shows I have a listener on

I changed $server_port to 21553 and logging is started up! The question
remains what is listening on port 11553, and why is it there?

#sockstat | grep 11553
root     perl5.8. 90509    7 tcp4       *:*
root     perl5.8. 90509    9 tcp4

#ps -ax | grep 90509
bash-2.05b# ps -ax | grep 90509
90509  ??  S      0:08.96 MailScanner: finishing batch (perl5.8.8)

So do I have an orphaned MailScanner child? A runaway MailWatch
listener? It's now over my head. I did not stop it yet in case someone
has a magical command to make it provide us with more information.
Oddly, both servers suffered the same issue within an hour of each
other, and both servers show the same state.

Three years now I've asked Google why they don't have a
logo change for Memorial Day. Why do they choose to do logos
for other non-international holidays, but nothing for

Maybe they forgot who made that choice possible.
