No one is receiving email notifications

I have them set up with noreply@jotform, yet none of us are receiving notifications. Before, it was only me getting them, now even I'm not. Please help. 

Hi,

I checked a few of your forms with the most recent submissions and the notifications are indeed setup correctly.  So, I checked our mail logs for the addresses in the associated notifications and they appear to be going through successfully. 

There are several different addresses in your notifications, all going to the same domain.  If they have all stopped at the same time, that leads me to be that your server may now be either filtering or blocking them.  If that is the case, here is our guide on what steps to take to remedy this:

This guide includes what servers to whitelist and things of that nature.  Also, have the people who are missing notifications check their spam email folders.

If you are still unable to receive your notifications once again, let us know and we will be happy to assist you further.
