A long time ago my fastmail.us didn't get accepted in places but I can't say I've had problems with that in recent years. Never had a issue with my me, I think people are well aware of the new tlds now.
As an extra bit of authenticity I've been smime signing my sent mail. Not encrypting, just signed. I figure that something no spamer is going to do and I’m hoping any spam filter will look at and pass it. Assuming they don't ignore it and make it a waste of time.
