Click on "Tools" and "Account Settings"

Select Outgoing Server (SMTP) on the left and make sure your outgoing mail server is set to smtp.yourdomain.com
Try changing the Outgoing Server Port setting from 25 to 26
Check "Use name and password" and type in your email name@yourdomain.com
Check "No" for secure connection
Click OK
