How about configuring sendmail on localhost to use the other SMTP as a
smart host?  If I get what you're saying, it does what you want and
has the added advantage that you can use any command line email client
- even good old mail.

For example, to use smtp.example.com as the smart relay:

  sed -i -e 's/^DS$/DSsmtp.example.com/' /etc/mail/sendmail.cf
  service sendmail restart
