Hi,
We have the following: customer complained he didn't get a notification mail after he entered a comment on a ticket.
I know that he shouldn't get a notification for his own changes so that is 'normal behavior' but the customer is using an generic email address on several user accounts and states that even when he shouldn't get a notification, someone else in the same organization should have (and they have the same email address as him).
Could it be that Jira detects that this is the same mail address as the reporter and therefore not sends a notification to that mail addresss?
