Tony,
I haven’t looked at the email headers since the other day, so pardon me if you have made adjustments. But there was an issue with the mx records not matching the box that emails are being sent from. The mx record for utehub lists mail.utehub.com while they are being sent from hosting.tkserver.com This will cause many email providers to mark the email as spam, even though they are on the same ip address. You can probably fix this with your smtp server config or create a spf entry to authorize hosting.tkserver.com to send mail for utehub.com. Setting up a reverse dns entry will also help email providers to see that the messages aren’t spoofed and are coming from the authorized server.
