How do I set up external email address from suppliers to log tickets within JSM

[Mihir Ruparelia]

Hello,

We currently have an email address set up which receives emails for our team and for any verified users in our JSM project a ticket is automatically raised. 

I want to capture in the form of tickets things like, subscription expiry and certificates that come from external 3rd party providers and systems, so if noreply@externalsuppier.com emails into our service email, that should generate a ticket. 

How do we go about doing this without opening up the project to everyone. 

If I created a user in our JSM project as a customer, with the service email address, could that then work? Any help or advise would be great.
