Re: SMTP Servers?

In my archive of around 2 million spam messages, 77% (±2%) have originated from dynamic, ISP-assigned IP addresses (nothing close to "nothing practically"). Most customer-facing email servers I've run into accept mail on the submission port (587), including Google's and Microsoft's. If you have a static IP, the port restriction is lifted, so if you want to run a mailserver that's a-ok.

Obviously this can vary from server to server for a number of reasons but this is what I was expecting.

As any properly configured and administered mail server should be, it has only been a standard for over a decade.

Tell that to some Canadian ISPs ... I left one for precisely this reason. They would not open port 587, telling me to get Rogers to lift the block. Yeah, right.

Some ISPs mail server setups are a joke and they don't know what they're doing. I'm not impressed with TSIs mail server setup either. But that is also why I said properly.
