RelayFax isn't checking the mailbox for new messages. This is usually caused by a back up of faxes that can't be successfully sent.
- Make a back up copy of the RelayFax.ini file, then open the original with Notepad.
- Change the value for this key:
MaxPendingFaxCount=10 - To something higher (say, 20).
- Save the file, and restart RelayFax
