Re: Comcast decides to block port 25 IN and OUT with no notice. said by Oedipus:Not quite sure what you do in "remote IT" ( ) that requires port 25, but as soon as you tell Comcast that they will come right back and either say a.) tough cookies, or b.) get a business class connection.
That blog post says "Upon request to our Customer Security Assurance team this block can be removed, enabling access to use port 25 for other email domains"
I need port 25 open to test to make sure the mail servers will accept a connection on it via telnet. If all servers blocked port 25 email would cease to function. |

Boynton Beach, FL | No, but it is very common for ISPs to require their subscribers to go through their own mail servers or use an alternate port that typically requires authentication to contact remote SMTP servers. This really isn't something new.
As was already mentioned, a business connection from Comcast does not have this restriction or a remote intermediary host or VPS can be used to perform the required tests. |

I can do that. I am going to contact them and see what they say tomorrow. It says in the blog post that they will but we will see. |
