[Exim] ORBZ and Mail

    I hope that you are well, we have been black listed by orbz, they send a
bogus message as a test of the form relay%orbz.org@??? and we would
like to reject messages such as those as none valid mail as we donot use
percents in email address.

    We tried to use the percent_hack = * option in the hope that our relay
would see that we have no local domain such as relay@??? and out right
reject it. Exim converts it into "relay@??? instead of
relay@???@uleth.ca or even relay@??? which would be a bad address
and exim would reject this message.

    Or if anybody can give me some pointers on how to get un-blacklisted
that would be great. Our uleth mail is of the form
firstname.lastname@??? and some local domains such as cs.uleth.ca may
have addresses of the form lastname@??? . We would hate to perform a
check via LDAP at our relay checking level as our ldap servers are seriously
bogged down or some domains such as cs.uleth.ca have no LDAP system in place
for us to make such a check against.

    Any help would be greatly appreciated
