Hello, I am currently running the Traps ESM v4.1.2 console and core on a single Windows Server 2016 environment. I have been unable to get email notifications to send. When I send a test message within Settings > ESM > Email, I receive the error "Failed to send test message." My organization is using Google Apps / G-Suite, and I have ensured that our smtp-relay rule allows for all addresses to send through SMTP without requiring SMTP authentication or TLS encryption. Within the email settings on the ESM, I have provided a valid user account and password. I tried using smtp-relay.gmail.com and smtp.gmail.com on ports 25, 465, and 587. Palo Alto Support has asked that I provide logs from Google's servers, which is not possible. Google support has assured me that nothing on their end should block smtp relays with my rule enabled. I am able to see the smtp traffic leave my network when I attempt to test notifications on the ESM. I also have several other services running on my network that use SMTP relay through Gmail and have no problems. Has anyone else had any luck with enabling notifications with Google Apps? Is there a log file that I can view on the ESM that is specific to SMTP / Notifications? I would appriciate any advise on this issue. Thank you.
