Yep, and he'll tell you exactly what he thinks of
uucp/rmail/etc... :-)  "UUCP is dead" is pretty much what he'll
say... :-)   Whether or not he's right is another matter... :-)

Anyway, there **is** a very good reason for "^From " line, and a very
good reason for insisting on it.

Each item of mail has at least 4 addresses.  The envelope sender, the envelope
recipient, the "to:" line and the "from:" line.

The envelope recipient is passed on the rmail command line, eg: "rmail
foo!bar!baz".  The envelope recipient is passed in the "From " line.

Sendmail needs these addresses to correctly function when errors
happen, otherwise you get horrible things happening like bounced
messages going to entire mailing lists, or the sender of mail to a
mailing list getting all the error messages etc etc.
