If your system does not have this app available, you can install it via the Marketplace.

There are two primary mail settings needed for a ClearOS system. The Mail Domain is the default domain used by mail services:
It is the “example.com” bit of the email addrss me@example.com.
The Mail Hostname is the default hostname used by mail services. For example, the SMTP Server (if installed) will reply to other mail servers with this hostname.

The hostname of the SMTP server to connect to.
The port to used to send the initial connection request on. SMTP usually uses port 25, but the app also supports using SMTPS (SMTP with SSL) on port 465.
Encryption protocol to use when connecting to the host server. Use TLS for SMTPS on port 465. STARTTLS on port 587 is not supported.
A valid username to authenticate to the server.
A valid password to authenticate to the server.
The default sender address to use for system generated outbound mail.
Once you have configured the mail settings, it is time to ensure e-mails can get through successfully:
