Wild guess: have you enabled filter_recipient processing by running
mimedefang with the "-t" option? (or by specifying MX_RECIPIENT_CHECK="yes"
in the appropriate startup script).

That is only one of the causes, probably. You can use a smarthost,
however.

You are testing here against the recipient given by the external
relay. I noticed in the headers below that you are actually forwarding
to [EMAIL PROTECTED] You might want to make the same translation
before checking, by adding:
$recip =~ s/\@(mail\.)?maidment\.com\.au/[EMAIL PROTECTED]/i;
... or something similar.

Apparently you are rewriting to [EMAIL PROTECTED] If this works for
known users, then maybe you added those users to something like
virtusertable? If so, maybe you forgot to add the catch-all entry at the
end of virtusertable, saying:
@[192.168.2.5] error:"5.1.1" No such user
