Hi, I have called xfinity multiple times and have been unsuccessful with contacting the department to unblock port 25 and would like to ask for assistance.  

xfinityCSAEmail -help please

Why do you need port 25 unblocked?

Hi there, @norseman40! Email is used for important communications and Comcast wants to ensure that these communications are as secure and as private as possible. As such, Comcast does not support port 25 for the transmission of email by our residential Internet customers. Much of the current use of port 25 is by computers that have been infected by malware and are sending spam without the knowledge of the users of those computers. I hope this info helps!
