FairEmail does that even better, though unfortunately it's mobile only. There's a setting you can enable and then it will, when replying, match the email address to which the email was sent. I so sorely miss this on Thunderbird because I literally never use the default email address (everyone has a unique address so I don't need to filter, aka have my computer guess what's, spam). There may once have been an extension but if I do remember that correctly then I expect the developer gave up after fixing it for the fifth time when they broke backwards compatibility again.
