sendmail fails to deliver to livemail with policy bounce

Hi list,

I've configured up a webserver, it server exists only as a webserver
and as such PHP is doing all of the sending using sendmail. I have a
problem whereby any mail sent to hotmail (livemail) addresses gets
rejected with the following bounce:

Which would appear to be correct enough to me.

Obviously in both examples above, www.MYHOST.com.au is the valid
hostname and XXX.XXX.XXX.XXX is the server IP address. I've set up an
A record and a PTR record so forward and reverse DNS lookups work
fine.

Let me know which configs/logs to post for diagnosis.

Please help.

Thanks,
Liam.

Your configs/logs won't help, because the problem isn't on your side.
Those of mx2.hotmail.com might be helpful but I doubt you'll be able
to get them.

> Please help.

The server mx2.hotmail.com rejected your mail for reasons of its own
that have nothing to do with technical problems. (That's what "policy
reasons" means.) Me and you can only guess what those reasons might
be.

Did you look at the URL given in the message? Perhaps you'll find
some hints there on why they rejected your mail.
