Hi @riahc4

May I recommend that you don’t use Sendmail, but use something like Postfix, which has a much better security track record? It’s a drop-in-replacement for Sendmail.

I’m not sure if CentOS comes with the wizard, like Ubuntu does, but run the installation:

sudo yum install postfix

Then have a look at the Ubuntu tutorial, but ignore the two first sudo apt ... commands and skip Step 3:

Postfix is a *mail transfer agent* (MTA), an application used to send and receive email. In this tutorial, we will install and configure Postfix so that it can be used to send emails by local applications only — that is, those installed on the same server that Postfix is installed on.
