This is probably nothing to do with wordpress and everything to do with spam protection methods ... are you allowed to send email for that domain? Trying to send from x@gmail.com will definitely get you marked as spam - google SPF records for why, then make sure you have one. Make sure your email comes from a reputable domain that's installed properly on your server.
