I think you misunderstood me, if zendesk receives a mail from an email address it does not have it should reply with "We don't have this email address, you can add a secondary address if you cannot send with the address you have registered with". It should be one check box in the GUI.
Now it works. Thx!
There was no misunderstanding, we will not be doing something like that because we accept tickets from those who don’t have accounts. If you want to get your ticket prioritized, or make changes to your account then we ask that you use an email address that is on your account.
Hope that explains, thanks.
