Is this a surprise? 'froggystyle.org froggystyle' forwards *all*
addresses ending in froggystyle.org to the user froggystyle.

If you want mail for some froggystyle.org users to be delivered
elsewhere, you need to make more specific entries for those addresses.
Example:

    froggystyle.org froggystyle
    rootfroggystyle.org root
    postmasterfroggystyle.org postmaster

Postfix processes the aliases maps only when the recipient resolves
locally (mydestination/inet_interfaces). The virtual maps are
applied much earlier, so they can affect delivery to other domains.
