Would work best if we package up FF accounts though...that ask has been sitting for a hot minute. I wonder at this point if it's better to pack a whole bunch of these FF services into one mega-container or doing them each individually. Probably the latter, though configuring them together feels like it shouldn't require manual input either, but at this point that seems unavoidable. Maybe I'll get to it sometime soon, but my list is getting pretty long.

I guess the sending & receiving part is already covered with Cloudron allowing to send from any made-up email under a domain and the catch-all.

I can't think of any use-cases that adding +something to the first part of any email address couldn't do, but all for things that increase privacy and data protection.
