Hi,  
  
  
  
Our test server security prohibits unknown IP addresses to access our server. I am working on a webhook for the email open event in mautic with regards to this, I need to identify what IP address that mautic will be using to send post request to our testing server.  
  
Do you have a list of IP addresses that the mautic webhook will use in sending HTTP Post request to our server?  
  
  
  
Thanks.  
  
  
  
Best,  
  
Paul
