If the recieving server answers on SMTP, AFAIK qmail is _obligated_ to
talk to it -- if it cannot accept mail, it should not accept
connections. Whether or not this is a requirement, this is the way qmail
behaves. The recieving servers are being silly -- if you're too busy to
accept connections, why open a connection to say so??

See above -- qmail is looking up all three, and talking to the best
preference. What is the receiving MTA for this domain? I'd like to know
for future reference -- it's behaving quite badly...
