We are using Clear Quest as a defect tracker in our project. The project has two groups, servicing company group and client group. I belong to the servicing company group. If any user belonging to any of the 2 group modifies anything in CQ all members will get a notification mail. (This is by using Email rule creation and configuring the user ids) Client is using different SMTP server. And servicing company is using a different SMTP server. The problem is that if a member of the Client group makes any modifications then all members (both the servicing group and the client group) configured in the Email rule are receiving the mails. But if a member of the servicing group makes any modifications to the records then the Client members are receiving notification mails but not the servicing group. Can anybody think of a possible reason for this?
