Symptoms
Notification emails received by users are all from the same "person" when you look at the From address. This address is generally that of the outbound emails for that project.
Diagnosis
Check your email headers and see if the Reply-To is correctly set.
Cause
This is actually caused by Outlook + Exchange + AD, not JIRA. Outlook clients only on Windows try to compare the From name with the email address, if they don't match what's in the Global Address book, it strips off the name and only displays the (JIRA) jiraoutgoingemail@example.com in the view of the email.
Resolution
To work around this issue, you must allow the host that JIRA is sending emails from to be trusted without authentication. Then remove the Active Directory jira user from authenticating in the outgoing mail server.
