Matt, recall that sendmail passes each recipient address through ruleset 0
to find a {mailer, host, user} tuple.

Tuples are sorted by mailer and host.  You say that you're using smail, so
it's likely that all your tuples resolve to mailer==smail.  But be sure
that all hosts resolve to the SAME CONSTANT STRING.

You might expect that an address of the form "matt@srs.uucp" should resolve
to {mailer=smail, host=srs.uucp, user=matt}, but this is wrong.  
Instead, ruleset 0 should resolve this address to
    {mailer=smail, host=SomeIgnoredConstantString, user=matt@srs.uucp}

Now sendmail's sort phase will respect the "sumtiple recipient" flag you
mention.

Aside:
    Sendmail has changed for the worse in recent revisions; more than ever it
    insists upon passing TRANSPORT addresses through rulesets for HEADER
    addresses.  This point is a bit subtle and counterintuitive.  A close
    inspection of 4.3BSD sendmail' internal ruleset invocation will show
    that for most configuration files the user part should contain the
    complete domain address (not just the local-part).  Thus the solution
    I propose to Matt isn't merely an optimization.
