Hi,

I have tried to reset to default the email addresses in notification settings but after reset i keep getting a set of email addresses i want to delete.

I have also cleared cache via devel and performance to no avail.

I searched the db as well but couldn't find reference to these email addresses i want to delete.

Can anyone tell me where they live in the db or how i can erase them via the website?

Thanks
