Is it possible to have multiple incoming email domains?

Hi there!

I’m wondering if it’s possible to set multiple authorized incoming email domains for Discourse?

I’ve set up my instance to allow incoming emails from, but I am hoping to allow our partners to set up specific incoming email domains for the categories and groups that they manage on our site. For example, one of our partners is a community organization with their own domain name and if we give them a category to manage their support requests with, it would be best if their members can email an address on their own domain instead of the base domain for the platform.

I realize that this is more easily done if I set up multisite and give each partner their own DB and URL, but the domain auth is an ENV config for the mail-receiver container as well as an admin config for the app itself, so I’m not sure what the best approach would be.

Any suggestions?

Have them configure their Neil server to forward the email sent to xxx@yyy to any address on your domain. Then configure the group for xxx@yyy.
