Dear Randy,
If it's practical, I'd use Python's smtplib. It's documented at:

http://www.python.org/doc/current/lib/module-smtplib.html

Since it uses a socket connection, it doesn't require that the MTA be
sendmail and the MTA doesn't have to be on the local machine.

If you really want to use a local copy of sendmail, you could open a
pipe to it and invoke it with the -t option so that it will read
the recipients from the message. Something like (untested):

p=os.popen("/usr/lib/sendmail -t","w")
p.write(msg)
p.close()

Your sendmail may well not be in /usr/lib. If you need to specify
the recipients outside of the message text, they can be put on
the command line (again untested):

p=os.popen("/usr/lib/sendmail a at example.org b at example.org","w")
p.write(msg)
p.close()

Regards,
Matt
