That doesnt make sense Hmmmm The Dude :) Acronym BOY 01-02-2003, 09:21 PM Originally posted by The Dude* Why would they block port 25???

What if someone spams several billion addresses via their ISP? ISPs block everything out going on port 25 out of their networks so you can't do that. Than they force you to use their mail server and limit how much mail you can send out. |
