I have Outlook 2011 set up as my primary e-mail on my MacPro desktop. I recently set it up  on my laptop for traveling. The laptop account will receive mail but it won't send mail. It displays a variety of error messages like "relay not permitted".

I have tried changing the settings for the outgoing server, but nothing seems to work.

I would appreciate any advice

Here is the problem code:
