Re: Mail notification faulty ?

Check if the My Changes option in the user's profile is Notify Me. The default value for this property for all users can also be set under Administration > User Defaults
Check the project permissions under the project's permission scheme. Users must have Browse Project permission for the project to which the issue belongs. If you're using Issue Security Levels, ensure they are members of any Issue security levels that have been applied to the issue.
Inspect the Mail Queue under Administration > Mail Queue and see if notifications are being queued. You can adjust the Mail Queue Service interval to a longer period for troubleshooting purposes. Inspect the Error Queue tab for any errors. ... t-training ... t-training
