Thank you for the welcome, gentlemen.
Bruce I just tinkered with the settings and on my MDA and the t-mobile tech told me to leave the authentication part blank. Oh well we'll ignore what he said. LOL.
So I just ticked it and put in the relevent password and username. I still got a message that the operation had timed out waiting for the server when I tried to send an email.
So this will seem a silly question but do I need to do something on my cpanel to allow authentication?
I'm a little stumped why it's just TCH domain I'm having problems with.
Thanks,
Dina
