[Sidewinder] Yahoo!Groups mail bouncing

We are having an issue from time to time where mail from Yahoo!Groups is
bouncing off the firewall.  The problem appears to be that the message
header (as opposed to the SMTP protocol envelope) has the form of:

	Yahoo!Groups <variable-stuff at yahoogroups.com>

And is bouncing off of the rule set:

	SLocalCheckUnqualifiedAddr
	R$* % $*        $#error $: 553 percent hack not allowed.
	R$* ! $*        $#error $: 553 uucp addressing not allowed.
<<<<<<<<<<<<<<<<<<
	R$* : $*        $#error $: 553 source routing not allowed.
	R$+ @ $+        $@ OK

	R$* postmaster $*       $@ OK
	R$* undisclosed-recipients:; $* $@ OK
	R$* Undisclosed $*      $@ OK
	R$* Admin $*    $@ OK
	R$+             $#error $: 553 $1 is an unqualified address


I am thinking that the cure (cinching it down as tight as possible) would
look like:

	RYahoo ! Groups < $+ @ yahoogroups.com >		$@ OK
	R$* ! $*        $#error $: 553 uucp addressing not allowed.

Comments?
