A few days ago my ISP blocked my outgoing TCP connections to port 25 - except to their mailserver. After a few calls they agreed to let me also access my domains mailserver (turned out they just allowed it globally to all their customers...). I sometimes use my domains mailserver or my ISP's, but at times, e.g. when I want to have the delivery session to the final recipient mailserver logged, I let my SMTP client go all the way directly. They claim they did it to fight spam - which is plausible, but breaks their claim to deliver "unlimited access" in pieces. And since no spam comes out of here, I do not like what they did. Not something I would go to war for, but I will not ignore this lightly either. Any observations from other parts of the world? (I am located in Sofia, Bulgaria).
Thanks,
Dimiter
P.S. Hint: if you don't know whether your ISP blocks your outgoing SMTP connections, try to connect to my domains mailserver, telnet://mail.tgi-sci.com:25 . If you see a response (one line), you are not blocked. Type in a "quit" command to close the session gracefully.
