"Once you have SPF/DKIM in place and make sure your IP isn't already on a blacklist for some past "

you'd think that it would be this simple, but it's not. I have had SPF/DKIM set up from day one, a totally clean IP, doesn't show up on any block lists at all, yet i'm still having some problems delivering to certain ISPs. Verizon is the biggest problem right now. I had problems delivering to Gmail because my server didn't have a good enough reputation. Everything from my IP was going right into the Gmail spam folder and there was nothing that I could do about it except sit back and wait. It took weeks for Gmail to finally decide that my reputation was good enough.

It's scary just how much power Google has over many things email these days.

Now I have to convince Verizon that my IP is not a dynamically assigned one.
