Slightly OT: you should not bounce, but reject during the SMTP dialogue.
What if some spammer abuses your wife's address as sender address? Your
wife would get your bounce and maybe will have a serious discussion with
you afterwards ;-)

Oh, I DO reject during SMTP...97%-98% of connection attempts are
rejected by my servers. I have built a rather elaborate but effective
process that adds entire netblocks to be rejected upon receipt of spam
from specified countries. If I ever get a customer who wants to do
business in China, or Russia, or Korea, I'm going to have a problem.
Anything that gets past the by-country blocks is then scanned, with
about a 60% rejection rate, but I'm only scanning 1%-3% of the attempted
connection count. Only stuff that gets past all that gets bounced...AND
reported to the originating ISP.
