Cable modems and email blocks
: Cablevision sometime ago blocked Port 25 for outgoing email, forcing me to use their email server to send (with no apologies from them, of course, when their server is down). Every damned day, I curse them when I take my laptop back and forth from home to office and have to switch outgoing addresses. That’s a great customer relations positioning: The company you curse every day. I know nothing about the tech issues behind this. David Isenberg knows everything. So go read his story about this here.
