I am a newbie to sendmail. I have a server running redhat that I now want to make my smtp server for 5 machines on my local network to use as their smtp server. I've enabled the sendmail service and verified that it is running. I can telnet to it on port 25 from the console, but I can not telnet to it from another server.
The server has full access to the internet and can resolve hostnames.
To test it, I configured outlook on a workstation and told it to use mail.mydomain.com as the smtp server. When I try to send mail, I get the following error: "unable to connect to the server".
What am I missing here.
