Hey there, 

 

new to using HubSpot. Have integrated all our Shared mailboxes and my personal one through Office 365 however every time i try and send an email through HubSpot it shows as sent yet I recieve the following error automatically. 

 

Diagnostic information for administrators:

Generating server: CWLP123MB2898.GBRP123.PROD.OUTLOOK.COM

Does anyone know what HubSpot's IP address is for email sending in order to get it delisted?
