Agreed. In this case, all it was getting (correct me if I'm wrong) 
was a TCP ack for the establishment, not an SMTP greeting. no 
"conversation" ever happened. Hence qmail should not assume an SMTP 
server is successfully running, and should drop back to secondary MX 
record(s). If it got an SMTP greeting, maybe queuing the message 
would be more correct, but it isn't.
