Source Make Sendmail accept mail from external sources
When you're setting up servers the last thing you want to have to do is put in an all nighter in order to get Sendmail accepting email from outside of your local network. If you're new to Linux this can be a real nightmare. The good news is once this is configured, it'll just keep on working until you take it down. But getting Sendmail to the point where it is working correctly can be a real nightmare.
In this article I will give you a step by step setup for getting Sendmail to accept email from outside of localhost and your own LAN. This will require you to manually edit some configuration files and you will need root access (or sudo access) in order to do this.
