We just upgraded all of our servers to 2.4 and are noticing some odd issues with Email Notifications:
1. If a project is watched for 'new changes' a notification is not received for it being uploaded
2. If a reviewer is added via the web interface a notification is sent to them
3. If a user comments/reviews a change via the web interface that I am a reviewer on or watching a notification is sent.
4. If a user comments/reviews a change via ssh, the notification is not sent.
5. If a user abandons a review from either web or ssh, the notification will be sent.
Most notable here are (1) and (4) where notifications are not being sent.
I verified this by running 'tcpdump' on the server while performing these actions. During the scenarios with notifications failing, no connection was ever made outbound to our smtp server.
We had upgraded from 2.3 where these scenarios performed normally and have not changed any of the configuration.
Thanks for any assistance you can provide.
