NASIL ? 550 permanent failure processed as Soft Bounce

[XC_Robot]

This bounce message is incorrectly processed as a Soft Bounce:
Code:

Action: failed
Final-Recipient: rfc822; xxx@evansinc.com
Diagnostic-Code: smtp; 550 permanent failure for one or more recipients (xxx@evansinc.com:550 5.4.1 Recipient address rejected: Access denied. For more information see https://aka.ms/EX...)
Status: 5.3.0

This clearly should be treated as a hard bounce.
