Original Post
We are running an SS20 Mail host using Sendmail (outside of
firewall). Does anyone know how to block unauthorized mail forwarding
from other ISP mail hosts ie. through daemon switches or sendmail.cf
parameters? Will summarize. Thanks.
Many Thanks to:

The majority agreed that new rule sets in sendmail 8.8 will block
mail forwarding by spammers. The following sites provide further
information.

head.
