DNS - Sendmail - confusion...

4 Apr 2004

      Hi,

I am configuring sendmail(oof) for the umpteenth time but this time on an
internet server.

My MX record is pointing at mail.my.domain

Sendmail can and does accept mail for mail.my.domain

Sendmail is configured to masquerade like so: user@my.domain

Sendmail refuses mail sent to user@my.domain

The error is:
x.w.y.z does not like recipient.
Remote host said: 550 5.7.1 ... Relaying denied. Proper
authentication required.
Giving up on x.w.y.z.

Can someone give me a cluestick?

Thanks in advance,

Todd McGuinness
