Android 10 (at least on my Pixel 2) doesn't have a native email app (other than Gmail), though of course there are lots of options.

Fairemail let's you specify different reply from addresses (if allowed on the server). I use this with mailfence.

last time i checked, gmail supports generic IMAP accounts as well.

But the smallest sync interval is 15 minutes and it won't sync sub folders until you open them.

It's not usable for real work, and I'm pretty sure that's how Google likes it.

But then you're using gmail.

we were talking about the android app, not the web service.

said android app supports generic IMAP accounts and doesnt need to be paired to a google account to work with them.
