sendmail Configuration

sendmail Configuration: "22.3.3 /etc/mail/local-host-names

This is a list of hostnames sendmail(8) is to accept as the local host name. Place any domains or hosts that sendmail is to be receiving mail for. For example, if this mail server was to accept mail for the domain example.com and the host mail.example.com, its local-host-names might look something like this:

example.com
mail.example.com

When this file is updated, sendmail(8) needs to be restarted to read the changes."
