I am getting spammers using domain names located on our servers and do not
understand how to stop them from passing their mail thru the servers.
The authorized clients who use their servers for mail come in to the servers
from many many different isp's. What I want to do is allow them to send and
receive their mail thru their domains but deny access to anyone else.
What do I do?
I seem to not understand the SMTP security idea in IMAIL
ANy and all help would be appreciated to stop this problem.
