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. On 07/31/2023, we started to edit all projects' Reply-To address field and use their '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.
