Having trouble with mail settings

Greetings - I've asked my host for the info to populate the settings, and they are:

SMTP Host/IP: truthsimplicitylove.com/ - the mail server(MX record) you're using for this domain
SMTP Port: 465
SMTP Username:    username@truthsimplicitylove.com - the email account you'd like to have listed as the sender
SMTP Password:    Use the email account's password.

I tried the domain with and without mail. and still just hangs when using the "test mail" function. I setup a dedicated email account and got my cPanel info email so it works.

Thanks very much,
