sendmail mail relay backscatter issue.
...allows all mail to be accepted for the domain before the attempting to
send it on for final delivery which causes NDR and backscatter for those
domains which do not have a catch-all account.
I have looked at adding "To:user at domain RELAY" to the access map and also
adding "define(`_RELAY_FULL_ADDR_', `1') " in the sendmail.mc and running
make -C /etc/mail but this has no effect on the sendmail.cf file. My
understanding is that if I can get sendmail to accept this undocumented
feature then all will be fine as I will be able to use the access map to
allow mail to those specific use...
