You sent a similiar query about this a few weeks ago, did you not?
Harald Hanche-Olsen said ``As far as I can tell, this falls into the
`this cannot happen' '' category. I was able to send email to an
address at eagle.co.nz, which apparently mail.renaissance.co.nz was
having trouble delivering to, using our qmail 1.03 server. Hence,
make sure that the version of qmail they are using there hasn't been
patched or modified in some way.
You said the renaissance.co.nz mail server behaved as below, which
would be mighty strange for stock qmail (logs from eagle.co.nz's mail
server, apparently):
