Hi,
Because of COVID-19, some co-workers were temporarily laid off and their email address deactivated. It seems that during this time, JIRA email server continued to send email notifications and ended up blacklisting the email adresses in question because the emails kept bouncing.
The person is now back and won't receive her notifications.
We checked the notifications assistant and everything is fine. We tested the same profile with another email address and it is working fine. We checked the email's black list, blocked addresses and spam folder and nothing.
The problem really seems to be on the JIRA email server side.
How can I get the email address to be removed from blacklist/quarantine? Can I read JIRA support for that?
