Outlook 2010 can receive but can't send messages...

Outlook 2010 can receive but can't send messages...

Outlook <> comcast email was working fine earlier this week.

Seem to be able to still receive mail from comcast but Outlook cannot send.

Get the following error message:

 

Task 'xxxxxxxx@comcast.net - Sending' reported error (0x800CCC6F) : 'Your outgoing (SMTP) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).  The server responded: 554 omta01.westchester.pa.mail.comcast.net comcast Port 25 not allowed -

 

I tried changing the outgoing port but this did not solve the issue. 

 

Actually, my incoming server is setup for the company (suncoasttours.com). Outgoing is setup for comcast. I receive emails with no problem. But whenever I try and send, I get the above error message.  :-(

"554 omta01.westchester.pa.mail.comcast.net comcast Port 25 not allowed" sure looks like Comcast is seeing you trying to connect on port 25. Please see http://customer.comcast.com/help-and-support/internet/email-client-programs-with-xfinity-email/.
