Description
Summary
Some users are unable to receive email notifications to their Atlassian accounts.
One of the sendgrid IP dedicated to Atlassian is blacklisted by an external system: https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a168.245.65.50&run=toolpage
Removing the block does not help. Since the sendgrid IP is blacklisted, the user is moved to blocked list again.
Workaround
As a workaround customer can whitelist the IP's listed here
