Sorry, dave.  If that was the case, then the mail would say
'tailorme'.  The 'somewhere' is from rmail.

When rmail starts up it tries to find out where the piece of
mail arriving from stdin came from.  It checks a variety of
places, including the From_ line.  If there is no host in the
from line, then rmail looks for an environment variable which
identifies the sending host.

The University distribution of MMDF had rmail checking for the
variable "ACCTSYS", which is (at best) a very old convention.
SCO neglected to change the environment variable to check in
early releases of SCO MMDF, so rmail can't find the variable.

The MMDF TLS from SCO correctly looks for the environment
variable UUMACHINE.  If you don't want to, or can't, upgrade
your MMDF, then move /usr/bin/rmail to /usr/mmdf/bin/rmail,
and create a shell script called /usr/bin/rmail which sets
ACCTSYS equal to UUMACHINE and then execs the real rmail.
