I'm no expert at all but I remember a thread a few months back about
shorewall blocking a connection from abroad for no apparent reason.
Kinda sounds like what is happening to you. It turned out that the ip
address that was being used was a "bogon". I think they are addresses
that are not allocated yet therefore it is presumed that any
connection from these addresses is obviously somewhat malicious so
they get blocked. Don't know if qmail uses these "bogons" but if it
does then that could be it. Hope this helps...
