Site name dilema

[Beau]

I've changed the site name for the phrase key "pages+title+home" to be something which is good for SEO ie. Apples, Bananas & Oranges in Town Country | Fruit Barn

but the problem is, all my email templates that use {site_name} send out messages that say:

Thank you,
Apples, Bananas & Oranges in Town Country | Fruit Barn Administration

&

Thank you for registering on Apples, Bananas & Oranges in Town Country | Fruit Barn

when it should really just say Fruit Barn

The site name & home page title should be 2 different entries. Is there a way to do this?
