The error comes from the mail server that Sendmail tried to contact.
Nick, you need two things:
a) To set up a "smart host", a mail gateway that will receive all your
outgoing mail. This is usually your ISP's mail gateway.
b) To set up envelope-address masquerading. That is, to make Sendmail use
a MAIL FROM command with a sender whose domain is valid. You can easily
set this up after reading /usr/src/contrib/sendmail/cf/README and use
the following FEATURE's in your sendmail.mc file:
MASQUERADE_AS(`domain.address')dnl
FEATURE(`masquerade_entire_domain')dnl
FEATURE(`masquerade_envelope')dnl
