#
# written 1998-11-xx by Moritz Barsnick <barsnick (at) gmx (dot) net>
# updated 1998-12-22: added "-m" option for grepmail
# added "exit 1" to trap
# updated 1999-01-04: added check for empty "mailbox" (don't open mutt)
# added messages
# added umask (to keep others from reading your messages)
# updated 1999-01-19: added trap for SIGPIPE (any other suggestions?)
# updated 1999-07-05: added $TMPDIR; we're still subject to races ($TMPFILE
# might exist)
# updated 1999-11-29: have mutt open the temporary mailbox read-only -
# there's no use in editing it anyway
