Port 587.


So is it time for ISPs to start blocking port 587 too?

If the complaints are going back to the IP address anwyay, why shouldn't
an ISP force it subscribers to go through the ISPs mail servers so it can
control any messages sent by its subscribers?


Because, maybe, I don't think it is a good idea for someone else to CONTROL
any messages I might send. Who will control the controllers?
