Unfortunately, that doesn't achieve the desired result, because sendmail
will proceed to add one Apparently-To: line for every person to whom the
mail is being sent.  Not only does this often result in several hundred
lines of headers, it also advertises the names of everyone on the list,
which is generally the very thing the sender is trying to prevent.
