Boonville, NY | Different port, same problem If you can configure to a different port, what then has blocking port 25 actually accomplished? Nothing. |

Exactly. Sometimes I wonder about OOL. They obviously don't use the money they make from me to pay for a team of good engineers and security experts.
I say track down the abusers/infected machines, send them warnings and shut THEIR service down. Now, instead of users like me being able to relay my mail off my web host, I am going to start relaying of theirs[not really but hypothetically]. And their mail server is SHIT to begin with...wonder what its going to be like now??

It stops currently zombie machines from sending emails to servers all over the world. its blocking the port on which the email servers listen. So it basically prevents the machine behind it a.k.a. Zombie from transporting mail to the main mail server which is where it is delivered to go to the user.

Actually, it accomplishes a bit.
Most providers don't allow annonymous connections to alternate ports. A form of authentication is typically required (though not always). This alone significantly reduces spam through that relay.
For servers using alternate ports for SMTP (authenticated or not) there is no standard and finding large numbers of these is difficult at best. If a spammer wants to attempt to use a single (or very few) smtp servers using unauthenticated alternate ports he'll be generating large amounts of messages throught that relay. This accomplishes the same purpose as OOL forcing users to use their own relays. Essentially, by blocking outbound port 25 OOL is preventing a large number of smtp servers from being used in a very short amount of time (a common tactic of spammers to avoid detection). |
