default "send" account in Mail?

OK, here's a Mail question.

I have ten different email accounts that Mail accesses. (When I was using Eudora these were called "Personalities"). I have that many email addresses because I wear a couple different consulting hats, I play in a couple different bands, and pretty soon it all adds up to ten email accounts. Such is my life. Mail all handles it reasonably well. As did Eudora.

A year later, here's the thing I keep tripping over, and I hope somebody here can help me.

Mail has a feature where, when you send a new message, it uses the last account that you used. If you're replying to an email you just read which was sent to Account D, the reply by default comes from the Account D email address. This is good.

If, however, you read a message from Account D, then go off and get a cup off coffee, and maybe do something else, then some time later compose a new email message, that message also comes from Account D by default. I would argue this is bad. Sometimes I catch this, but sometimes I don't, and I'll inadvertently send somebody an email message from the wrong account.

I would like to keep the "reply" behavior the same, but for new messages I would like to set a default account rather than have it use the last account I happened to read from.

Is this possible?

Thanks in advance.

 

Awesome! Why didn't I find this? This is exactly what I was looking for and it has exactly the behavior I wanted as described above.

Thanks very much!
