form not sending emails....

My forms seem to have stopped sending emails.

I have checked your email address and it is currently in our bounce list, this is why you were not receiving emails.

Here's the reason for that: 

Reason(s) : smtp; 554 IP name lookup failed. No PTR record found

I have  removed it and you should receive emails from your forms now, please check the guide below in order to know how to properly set up your email notifications to avoid bouncing: 

How-to-Prevent-Email-Bouncing-Related-Issues

Also, you could check and remove an email address from our bounce list by following this guide: How-to-Remove-Your-Email-Address-from-Bounce-List

You could also set up a custom sender email address by using SMTP, this way you will have more control over how the emails are sent and will use your own sender info, here's the guide: How-to-Setup-SMTP-for-a-Form

Hope this helps.
