I'm using Gmail (wonderful tool, allows me to also archive every single dom3 turn I ever come upon without worrying about the size of the turns), and I have no problems. Sometimes the turns take ~10min to get through, but rarely longer than that. Give me a PM if your turns don't get in before the time limit and I'll extend it a bit.

vfb has a good point with the ISP email, though it doesn't necessarily mean that only ISP emails would suffer from that, any mail provider with dropouts from network or buffered email sends (though, who would ever want to do that) might suffer from the same. I wholeheartedly suggest trying with other email address from a different provider (such as Gmail or Yahoo) to see if it solves it.
