The problem is that if that address were to end up in the aliases
file, since it starts with a '/' sendmail would attempt to open the
file with that name and put the message there.  However, explicitly
quoting the whole X.400 address for sprint.com to deal with:

"/PN=CHARLES.R.MARGE/O=ADLITTLE/ADMD=TELEMAIL/C=US/"@sprint.com

could be made to work, once we understand the security implications on
the mailhub.  It's not as simple as only restricting the first
character since
	foo@bar,/etc/passwd
is another address that would wreck havoc if we aren't careful with this.
