unblock TCP port 25

I have tried again and again to call customer service to unblock port 25.  NOT port fowarding but to allow port 25 through my modem.  This has been very frustrating.  I was actually on a call with someone who actually understood what I was trying to do and we got disconnected!!!  Then a few hours later of calls I still can't get this done.

I've seen several people have success by posting here, can someone PLEASE help and unblock port 25 on my modem?

I need this unblocked for work and testing while I am remote.  This has been VERY painful to try to get help on the phone... Can someone here please help me?

So i believe you must have business class service to get port 25 unblocked. Comcast doesn’t allow it on residential.

They absolutely will not unblock SMTP port 25 for you as they do not want their users sending spam, either intentionally or via a malware attack. Upgrade to Xfinity business if you really need SMTP.

If you must use SMTP try connecting with SSL on port 465 or STARTTLS on port 587.

Why are you needing to use an old, insecure, and well abused SMTP protocol?

VPN? There really shouldn’t be any reason your work needs you to unblock port 25 from your home internet for testing. This is what VPNs are for.
