I have a few accounts that I access with Thunderbird. There are a few times where I go to compose a message to a professional contact, then Thunderbird sends from my personal address instead. This may be a default behavior, but it's almost always a face-palm moment. I wonder if there may be some clever way to associate and address with a certain mailbox/account. So that if I send to that address, the collected history from Thunderbird would show that it was sent "from" one address and perhaps present that address as the default when composing a new message. Or some other clever way? Thanks.
