After adding and verifying a domain in Admin>Settings>Emails any email notofication from both Jira Software and Jira Service Management stopped working for all projects.
We reverted change we did for Jira Service Management (only email change we did), removed the domain, but still the email notifications are not working, not emails in Jira Service Management
Any other notifications via Teams, Web, Mobile App are working as expected.
Any ideas/suggestions?
