How can I restrict new issue creation to only allow people within our domain?

[Jeff]

We have a Service Desk project for our internal Help Desk, and users can send emails to this address to create new issues i.e. open a ticket.

This address is also used for the administration of software licenses, billing, things like that. This address regularly receives emails that are automated, basically spam or just not relevant to this Service Desk project, and every email creates a new issue. This causes the issue count to be artificially inflated, and it sends useless notifications to our Slack channel, etc.

Is there an easy way to restrict this so that only emails from @mycompany.com create new issues?

Jeff,

You'd have to have different emails addresses for your Admin work and for Help Desk.

You can only have email address per service desk.

So instead of having a simple setting which would just automatically close all tickets that don't match a certain domain - you want us to setup a brand new mailbox just for it?

Even that's not so much of an issue but you even removed the option of letting us create our own rules to do this. 

Why lmao?
