I use Thunderbird with 3 different email accounts. It's not rare for me to mistakenly send out emails from the wrong one because I was reading an email in that account before writing it. Now I'm trying to have Thunderbird automatically select the sender account according to the recipient, i.e. whenever a recipient's address is in a selected domain (*@hello.com), I want Thunderbird to automatically send that message from the associated account. Apple Mail does this, does Thunderbird have a similar function? I tried to tick a function that sounds like that (screenshot attached), but it doesn't do the trick. Any help will be appreciated.
