From my Sendmail Installation and Operation Guide:

..sh 3 "Apparently-To:"
..pp
RFC 822 requires at least one recipient field
(To:, Cc:, or Bcc: line)
in every message.
If a message comes in with no recipients listed in the message
then
..i sendmail
will adjust the header based on the
..q NoRecipientAction
option.
One of the possible actions is to add an
..q "Apparently-To:"
header line for any recipients it is aware of.
This is not put in as a standard recipient line
to warn any recipients that the list is not complete.
..pp
The Apparently-To: header is non-standard
and is deprecated.
