Yeah, I thought about doing this to get rid of these email domains.

I notice that a Discourse method creates `@no-email.invalid` emails:

> <https://github.com/discourse/discourse/blob/main/app/services/user_merger.rb#L364>

And in the importer base, it uses `@email.invalid` which is slightly different:

> <https://github.com/discourse/discourse/blob/main/script/import_scripts/base.rb#L869>

1. Are these two different “dummy domains” both ignored when Discourse must send emails?

2. Should I replace my non-working domain with `@no-email.invalid` or `@email.invalid`, or it doesn’t matter?

@pfaffman, I’m not sure to understand why I should remap in **posts** instead of changing the **user emails** … 🤔 These email addresses aren’t in posts, unless I’m missing something.

If it is a recommended way, I’d just like to replace my `@brokendomains.com` addresses in each profile by `@no-email.invalid` or `@email.invalid`. I can figure out how to do this, I just wonder which “fake” domain to use.
