As soon as the unencrypted e-mail is sent by the accountant, your
sensitive information might already be sniffed, somewhere between the
MUA/MTA of your account and the MTA you control. You could use a setup
like this to teach your accountant better manners, but your information
is out on streets none the less.
Seems like you are solving the wrong problem here.
