unblocking outgoing port 25

Hello, I saw in another thread that to get outgoing port 25 unblocked I should start a thread.

I need outgoing port 25 for my work from home. Some work computers that I need to access are only reachable on port 25.

@XfinityQuemekia​ Hi thank you for your response. I looked over that page and searched it for “port” but I didn’t see where I open the ticket to unblock the port? Please advise!

Xfinity does not support port 25 for outbound email traffic from residential accounts. This is because they block it to help prevent spam. We fully block port 25 for all residential email traffic.

It's very doubtful you will get port 25 opened.  A few people managed it, but that was a couple of years ago.
