I don't know what adds Apparently-From: -- I only found it in four
messages in my own archives, all basically forged. However, all of
these had both From: and Apparently-From: but they held identical
information.
The spam archive at http://www.spam-archive.org/ gave at least 50 hits
on Apparently-From but this could be a function of how the archive
works (i.e. people forward stuff to a mailing list which gets
archived; all the messages in my own archive were forwarded, too).

According to the sendmail book, the "Apparently-From:" header is added
by Smail 3.x when it cannot find any of the valid sender headers in the
message. The field used on "Apparently-From:" is taken from the
the message envelope. sendmail will create a "From:" header in this
situation.
