Such an application fault is

Such an application fault is generally caused by an issue where a TLS session fails to close properly. In this scenario, the email does deliver successfully, but can produce an application fault. In general, these application faults do not indicate a problem with the appliance, and shall be suppressed in a future release of AsyncOS.

With running 7.8.0 - which shipped on the appliance, you may benefit to upgrade to 8.0.1-023, or open a support request to have the appliance properly provisioned for 8.5.6 FCS, which may help to correct seen TLS issues, such as this.

I hope this helps!
