Supress Tracking For Mailing List Mirror

Is there a way to suppress Discourse’s replied-to emails when a category is a mailing list mirror? I want to pull in the conversations from Google Groups, which is working, but when a new reply is posted both Discourse and Google Groups are emailing the user.

Edit: For context, a user attempted to reply to the Discourse email they received and not the Google Groups email.


As a workaround I’ve managed to stop the outgoing notification emails based on their subject containing the read-only mailing list category at my email server. I’m hoping that we can get an additional checkbox when “Category mirrors a mailing list” is checked to suppress notifications and emails about replies in order to make the mailing list truly read-only.
