Email not sending or recieving

I have 2 email accounts. The one for my business (owen@cmtechnologies.biz) sends and recieves email just fine. The other (owent@taylorappaloosa.com) has not been sending or recieving email for at least 2 days that I know of. I have other email accounts (yahoo,Hotmail, Gmail) that I have been using to check send and recieve items to and from, so I have verified this extensively, sending emails to and from myself. any help on correcting the issue for. email thank you Owen T
