Subject: Re: Sendmail help please..
John,
You need to have permission from the other hosts in order to relay email
if I understood your question.
In the case that you want to setup your own mail relay you should need to create the
file
"relay-domain".
List the full qualify domains in this file one in each line.
# Hosts that will permit relaying ($=R)
FR-o /etc/mail/relay-domains
After you do the above restart sendmail.
I hope this help.
