Complexities of e-mail validation logic

Out of curiosity, are those popular services? I'm in process of setting up email on my own domain and it would suck having to fallback to Gmail if some service uses an accepted list of domains.

fastmail is reasonably popular. Gmail is bigger, but fastmail is big enough that they cannot be ignored, unlike when I ran my own personal server and often found myself in blacklists without any knowable way to get off.

I've had a couple places not take my .us domain, but almost everything is fine with my .org. The places I've run into that are really picky don't like gmail or other free email providers.

The one exception is Craigslist; if I email someone with my normal email, I never get a response. I always use gmail for that.
