[Evolution] Default sending account when replying

["a.gnome" <a gnome icewater org>]

I have quite a number of email aliases.  I've created a SMPT-only
accounts for each one in Evolution.

When I reply to an email, I would expect the sender address to default
to the "To:" (or "CC:") address by which I received the email.  

Instead, it always defaults to my personal (primary) email address, and
I either inadvertently send it (giving away my personal email address)
or have to hunt through fifty or so disordered email addresses in the
"To:" drop-down for the correct one.

I believe Evolution used to do this, but it no longer does.  Is this a
bug or an intentional change?
