I want to make it clear... I don't mind people filtering either 25 or 587, but, blocking both is highly unacceptable. Even more unacceptable in my opinion is hijacking connections to either off to your own man-in-the-middle attack server.
Owen, You must have been irked by the airport wireless in ABQ then. I couldn't figure out why my ssh connection was failing until I checked the DNS and relized that even after clicking "free access" button in a web browser they returned 192.168.1.1 for almost every name requested. :( I can understand blocking outbound tcp 25. I wish more folks did it. Blocking 587 makes no sense. The whole point of 587 is that its the authenticated mail submission port. Its of very limited use to spammers. Guess we'll have to move it to 443 too. ;) Regards, Bill -- William D. Herrin herrin () dirtside com bill () herrin us 3005 Crane Dr. Web: <http://bill.herrin.us/> Falls Church, VA 22042-3004
