I get the following error message when trying to send an email with attachment

Sending of the message failed. SSL peer reports incorrect Message Authentication Code. The configuration related to smtp.comcast.net must be corrected

How do I fix this?

Hello

Well, your configuration for your mail server is in the account settings, outgoing server (SMTP); click the Edit Smtp server button, if the port is 25 that's the main error, should be (probably) 465 (if it does not work check with Comcast documentation), and connection security should be SSL/TLS.

Thank you for your reply. I checked my settings and the port is 465 and the connection security is SSL/TLS. So I called Comcast and finally (after about 45 minutes) got a live person. They really didn't have an answer of how to fix it but they told me to use Comcast website to send emails when I want to send an attachment. So problem is indirectly solved LOL

Your problem is probably caused by a software firewall installed on your computer (AVAST or something like that). Try to configure it to stop network scanning of port 465 if you can, or disable it entirely.
