Sendmail Aliases/Groups

Aliases

To send an email to an alias edit:
/etc/aliases

name:          email@address.com

Groups

To send an email to a group of people:
/etc/aliases

groupname:     email@addres1.com, email@address2.com, ....

Once the file has been updated we need to updated the aliases databse.

newaliases

Restart Sendmail

As a precaution so sendmail sees the changes you will need to restart the sendmail service. I have made changes to aliases without a sendmail restart which has successfully worked.

service sendmail restart
