Do you have a procmail mailer in your sendmail.cf file?  (iow do you
have a 

        MAILER(`procmail')dnl

line in your foo.mc file?  If not, you need to add it I guess.
Then, do this:

        define(`LUSER_RELAY',`procmail:/etc/procmailrcs/some.rc')

and rebuild foo.cf .  Once you've done that, then this is what
happens to unknown users:

    $ /usr/sbin/sendmail -bt -Cfoo.cf
    ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
    Enter <ruleset> <address>
    > 5 foobar
    rewrite: ruleset   5   input: foobar
    rewrite: ruleset  95   input: < procmail : / etc / procmailrcs / some . rc > \
foobar < @ / etc / procmailrcs / some . rc >  rewrite: ruleset  95 returns: $# \
procmail $@ / etc / procmailrcs / some . rc $: foobar < @ / etc / procmailrcs / some \
. rc >  rewrite: ruleset   5 returns: $# procmail $@ / etc / procmailrcs / some . rc \
$: foobar < @ / etc / procmailrcs / some . rc >

whereas a known user will be handled like this:

    > 5 root
    rewrite: ruleset   5   input: root
    rewrite: ruleset   5 returns: root
    > 

Well, that might provide a starting point but I haven't tested it...
You may have $f rather than $g in your mailer definition (look at your 
procmail manpage and p.593 of the "bat book" (2/e) and decide whether
you need to change $f to $g in there, etc.
