10.0.2-020 11.1.0-054

Description (partial)

Symptom:
A corrupted workqueue still attempts to process mail but due to the corruption the message is not delivered. Since it is accepted the sender is unaware of the issue and no alert is generated to alert the recipient.

This enhancement proposes to attempt to deliver a 4xx banner and allow the sender to resend the message later with the hope it will deliver to an uncorrupted MTA.

Conditions:
Corrupted workqueue
