A little over a month ago we noticed JIRA Service Desk projects started adding what appears to be "ghost comments" on tickets. Each time an email is generated by the system, (via customer comment, agent comment, any generic event), the notification is scanned back into the ticket by JIRA and noted as "this user commented" or "this user changed status of ticket", etc. I believe JIRA Service Desk email handler is not discarding emails from itself to itself and it normally does.
A cursory look at the processing log shows for a project BEFORE the issues shows that all emails sent from a service desk project , that were scanned back into the service desk project, were being REJECTED with detail "The message was rejected because it was sent from JIRA" and the handler states SD sent from JIRA filter. AFTER this issue the same sort of emails we expect to be discarded show as SUCCESS with no details and the handler is Service Desk Mail Handler. Does anyone know how to turn SD sent from JIRA filter back on somehow?
We've seen this impact several Service Desk instances versions in including JIRA Service Desk version 3.9.3/JIRA Core 7.6.3 and JIRA Service Desk version 3.10.0/JIRA Core 7.7.0, the latter is a "vanilla" install with a single service desk project migrated over.
Found these answers and unfortunately wasn't able to find the SD sent from JIRA filter because Service Desk isn't showing up as a managed add on. https://community.atlassian.com/t5/Jira-questions/Unable-to-turn-of-SD-Bulk-Filter/qaq-p/219239
