Mail sent to "users" in /etc/aliases

[Bill Moseley <moseley@hank.org>]

My /etc/aliases file has entires like this:

    daemon: root
    bin: :fail: Unknown User
    sys: root
    sync: root
    games: root
    man: root
    lp: root
    mail: root
    news: root
    uucp: root
    proxy: root
    postgres: root
    www-data: root

When would mail ever get delivered *to* those addresses?  Will
anything break if mail can't be delivered to "www-data", for example?

I've been getting more spam lately addresses to common unix users, so
I'm thinking about rejecting mail to those users -- well, any user
that is not listed in a separate "valid-users" type of file.
