I have a certain project that contains tickets that do not send notification mails. I guess that the problem has something to do with user groups. Is this possible?

The tickets were created by some users that were added to the project as a group. That means I have created a group with those users and then added the group with a certain role to this project. Now, AFAIK when one of those users create a ticket no notification mails are sent to anyone. The affects also other users of this project that are set as observers or that are set with 'assigned to'. However, if those other users create a ticket all works fine.

Is it clear what I mean? I'm not sure, the problem could have to do with something else. I just suspect that the groups causes the problem.

Could I analyse anything else to provide you with more information?
