On 07/31/2023, we started to edit all projects Reply-To address field and use their 'projectkey@su-jsm.atlassian.net' and completed this task on 08/01/2023.
There was an issue where some email messages were not creating comments within tickets. The issue was the Reply-To address was incorrect and the system used 'jira@su-jsm.atlassian..net' as the Reply-To address. While the system managed to deliver most mail correctly, some email messages were not creating comments. This could impact additional comments and email and all messages need to be entered correctly. The Reply-To address needed to change to match the projectkey.
Now, all mail being sent from your project will have the projectkey@su-jsm.atlassian.net. Project Managers can review their Reply-To address in the project. Under Projects Settings, locate the Notifications link on the Left Nav bar. At the top of that screen will be your Reply-To address.
Please review you mail filters and ensure OT mail is sorting correctly as this change may impact your filters.
