Help with NO-IP Alternate-Port SMTP and WHM

Hello i am looking for some help

my emails getting bounced back from some email providers.

I purchased NO-IP Alternate-Port SMTP and that is supposed to resolve my issue.

I am Novice WHM User and need help.

Can anybody guide me to properly set up Authenticated SMTP Relay service with WHM?

i need to send emails through email relay and have all required data like port, server address, User Name and Password

please provide WHM step by step instruction on how to do it..

we struggled with returned emails for over a year from Hotmail, aim and others.....

Thanks

 

Thank you for your reply
I did follow that Instruction before i created that post

the issue is
that when i entered correctly all the info form the instruction

OUTGOING MAIL WORKS fine


BUT

INCOMING EMAIL STOPS working and people get Bounceback

As soon as i remove these settings everything gets back to normal ( Email is coming in and i can reply to those i can )

Why as soon as i use these settings i get NO INCOMING EMAIL?

these settings are for SMTP only???

How can i fix that?
