> The email had a From: header of DNAuser at auckland.ac.nz.
Are you sure it didn't come in with a From: header of just
DNAuser, with your own mail software appending @auckland.ac.nz
to any unqualified addresses it sees?
We reject mail with unqualified From headers. It stops a lot
We could not reject mail with @columbia.edu in the From.
Plenty of our users are on ISPs worldwide and put their
columbia.edu address as the sender. This battle was lost
long ago. We have to accept this even if it is a "lie"
about what account is sending the mail.
