A Novel Idea to Combat SpamIt's a well known fact that quite a bit of spam comes from the Comcast network. Now that Comcast has blocked TCP port 25 (the port used for e-mail sending), spam from their network has dropped 35%. Now if we could just convince other gigantic ISPs to do the same, life would be good. I know that geeks sometimes run SMTP servers on their home servers, but if they're smart, they'll just change the port used and they won't have any trouble. I know Bend Cable (oh, sorry, Bend Broadband) blocks at least ports 21 (FTP) and 80 (HTTP) so the server I have at home that I backup files from work to runs on different ports so I can still access it. Geeks are smart -- common users that have their computers zombied for spam are not. Posted by Jake on 06/30/04 @ 05:08 PM

You can't change ports to get around that, since the service on the remote machine would have to provide itself on a different port. Jake said on 06/30/04 @ 09:50 PM: D'oh. You're right, that would make more sense, and that's what they did (it wouldn't work for me because I routinely use an outside SMTP server on my laptop so I don't have to change settings all the time). They should still block it on the outside, just the same. Rick said on 07/01/04 @ 07:28 AM: They only block people that appear to be spammers, I assume by volume of mail going out. Regular users will not be blocked. Post a comment |
