Mountain Lion Mail, reply from address

Mountain Lion Mail appears to have reply to mail from address completely =
broken, but I'm hoping maybe this is just user error.

There are three accounts a@, b@, c@. Mail arrives into each of the three =
accounts. When I click on email in any of the three accounts and reply, =
by default the =46rom account is the same account received. There is a =
preference for this.

It used to be the case, those emails, if placed into Mailboxes (folders) =
per Rules, that you'd get the same behavior. If I click on an email in =
"Omni Admin" folder, and reply, the =46rom email account is set to the =
account that received the mail.

That is no longer what I'm experiencing. In all mail folders, replying =
causes the =46rom setting to always be from account a@. The first =
account. I see no setting to change this behavior. So what's been =
happening to me since the "upgrade" to Mountain Lion, I'm replying to =
listserve emails and the mails are bouncing because of course they are =
sent from the wrong email account.
