How to install PEAR Mail?

Hello!

I need PAER Mail package. How can I install it? (Hosting Plan: Linux Basic)

PEAR is already installed and is available for use, all you need to do is call it from your PHP script.

And how can I use it?

include('Mail.php'); or require_once("Mail.php"); do not work.

Sorry for any confusion. From what I understand you need to upload Mail.php. Then you can just use include() to call it in your script.
