Yeah exactly - last time I went through the trouble of setting up my own e-mail I decided it just wasn't worth it between PTR records, dmarc, and SPF. It's possible, sure, but takes away all of the old-fashioned enjoyment of quickly setting up a Linux box with postfix and on your way you were.

I don't have that problem and my mail PTR doesn't reverse to my mail domain, it reverses to my ISP. Maybe because I have a really old domain.
