To host your own mail server to send and receive messages you should have your own domain, and preferably a fixed public IP address. You should as well make sure that your Internet provider allows traffic on port 25 (SMTP).

Pegasus or Mercury do not by themselves provide any SMS feature. 

Hi!

I first came across Pegasus Mail and Mercury

when I used XAMPP server to test the web applications I developed. I have only

a very little knowledge of networking, so I don't totally understand some of

the terms used while describing the Pegasus Mail and Mercury. What I want to

know right now is this:

• If I install

  the Pegasus Mail and Mercury on my computer, and I don't have any e-mail or

  web-hosting account with any hosting company, will I be able to send (and

  receive) e-mails?

• Is it

  possible for me (or any other user of Pegasus Mail and Mercury) to send SMS

  with Pegasus Mail and Mercury? i.e. does Pegasus Mail and Mercury provide

  e-mail to sms feature?

Thank you.

Yours sincerely,

Yemodaniel.
