Its the port number! Change the port number!

I called Zain many times even went to their branches and talked to lots of sales agents and their technical support department.. All with no luck of finding a solution to the not being able to receive emails through email clients (Outlook, Mail…etc) problem.
This weekend when we were talking about this problem, Hamad told me something about changing the port, then Khalid told me that he’s been using Ego with no such problem, He also said something about the port number. Finally he gave me the port number he’s been using and.. just like that.. it worked!
My Gmail, Mac and personal domain all worked with outgoing server port #587.
Thanks a lot Khalid!
