Looks like you've got something wrong with whatever's listening to the 
mail port.  Exactly what's wrong is hard to diagnose from the log 
message (unless it's encoded in that long number), but I'd check for 
overlaps in your tcpserver, daemontools (if you installed this with 
qmail), xinetd, inetd, and sendmail (or any other stand-alone MTA) 
configurations, and check what's currently running via "netstat -lnp".

You probably have two services trying to listen to the same port...
