Oh right. The servers my qmail server was trying to talk to were saying:
delivery 6: deferral:
Connected_to_136.182.1.10_but_sender_was_rejected./
Remote_host_said:_451_<[EMAIL PROTECTED]>..._Sender_domain_must_resolve/
So this "Sender domain must resolve" problem is because the remote mail
server decided that this is a transient error, and the 451 code
communicates this to qmail. OK - so this is a bug in the remote server or
it's setup. I was wondering why qmail wasn't bouncing the mail back. Now I
know, thanks.
