Once an account is completely setup on Proofpoint Essentials User Interface according to the getting started guide found, the partners/customers should wait until the top of the 30 minutes for the changes to update across Proofpoint Essentials Network before testing the service. If you need a copy of the Getting Started Guide, please contact Support or your Reseller.


Partners/Customers should ensure that they have provided all the required information and the following have been configured (Any changes made will take effect at the top of the 30minutes).


If emails are not being delivered from one particular domain 

If you are not receiving email from a certain domain, it could be due to one of the reasons below


  • The sender is on one or more of Proofpoint's email blacklists. 
  • There is an issue with the senders SMTP server
  • Emails might have been detected as spam and should be visible in the users quarantine.
