Sorry you're having mail trouble! For your privacy, I removed the email addresses from your post, but appreciate you providing them for context when I looked iAnitially. It's possible the server name changed and the mac mail client is taking a bit of time to catch up. I would suggest reviewing your mac mail setup. Check your email settings in cPanel and, as an extra thing to try, please find out what your current server name is. Switching your mail setup so it uses your server name (usually something like secure###.inmotionhosting.com) is a good way to force the mail client to connect to the right place!
