I just use my own mail server!

I tried that, and got bounced by many recipients: ones own mail server often exists inside 'black holed' IP address domains, for the same reasons.


As Bob said, it depends on your ISP and the classification.

If they list your IP as 'dynamic', then it will often be black-holed.

The ISP we use assigns static IPs, and encourages the use of local mail servers.
They allow us control of DNS and RDNS on our assigned IP allocations on their DNS servers, and will delegate both forward and reverse DNS to our local servers if we wish.

If we configure our mail servers and DNS correctly, then we don't get blocked.

( Sometimes, the ISP's own servers do, due to silly automated blacklists messing up. It takes some work on the part of support to get them un-blacklisted. )
