Description (partial)

5xx SMTP code is given to the sending mail server instead of custom code when the recipient validation request fails due to timeout or connection error. Receiving ESA erroneously logs the expected custom code in its mail_logs.

Configure callaheadconfig to with "Validation Failure Action: REJECT with custom code".
