I had to write a script on HP-UX that would send an ascii file as a mime attachment but in such a way that a non mime mailer could read it. This was to satisfy all of our customers at once. Here it is...
#! /usr/bin/ksh
#
# This script takes two ascii files and mails them. One file is
# the main body of the message. The second file is sent as an ascii
# mime attachment. But everything is kept in ascii so that users with
# non-mime mail user agents can deal with it
#
#
# Options
#
# -t addressee (required)
# -a address (required)
# -b body (required)
# -s subject (optional)
# -A attachment (optional)
#
# mimetool -t "Joe Blow" -a jblow@abc.com -b body.txt -A attach.txt
#
# Here body.txt and attach.txt are files. The name of the body file
# isn't too important. The name of the attachment file is important
# since it will be sent as well as the contents. A Microsoft OS uses
# the name to figure out what to do. It knows what a .txt file is but
# it will get mixed up with a .junk file.
