this is a new install. Sendmail 8.12.10 on Redhat Linux Enterprise 9.0
The server is NATed behind a firewall, so it has a private hostname and IP. It is to be a relay for an internal Exchange server.
The Host name is "Priv", the DMZ domain is "Local.priv". The Public domain is "Domain.com". the Exchange box sits in "Domain.Otherdomain.com".
The goal is to send/receive mail and have it appear as "user@Domain.com". Can you advise the correct way to do this?
Also, what is the best way to test Sendmail and that this server is relaying correctly? I tried running the command line /usr/lib/sendmail with various switches, but that doesn't seem to work correctly.
thank you in advance for your assistance.
