rules not using all addresses for single contact

[hm chou]

Not all of my wife's emails are being organized by rules. I say "not all"
b/c only some are/some are not. For some reason, the rules are running based
off my wife's default email address -- but she has 3 (isp, business, yahoo).
Is there some way to get all of her emails to be accepted by a single rule.

I know I can do it based off words (her name, for instance), or separate
rules for each email, but that seems like a pain in the a**.

Thanks for any suggestions.
