Sendmail error: Unknown Address
Greetings,
I am running the version of Sendmail that ships with RedHat 9. My mail server is located on a small LAN. I have opened the appropriate ports on my router and my RH firewall.
The problem I have is that I can not send mail from a machine located outside of my LAN. If I try to access my smtp server from a machine located outside of my LAN, I get the following error: sendmail error: unknown address. The server did not recognize the recipients. Using the same username and password, and sending to the same email address from a machine INSIDE my LAN = no problem and no error. I can access my POP mail from both inside and outside the LAN.
Any ideas. Thanks for the help.
Dan
