There's no special significance to "$SENDER" with sendmail. If you
specify it in an alias, it will be treated as a shell variable and
probably equate to a null argument.
You're confusing sendmail with Majordomo. The example you're using
doesn't use any Majordomo commands. You're not using Majordomo
here, and Majordomo wasn't written to be able to do what you want.
What you want to do is not provided by any program supplied with
sendmail or Majordomo, though you could probably hack a one-page
perl script to do it. Auto-replying with a canned message is an
absolutely trivial thing -- you don't have to "switch" to another
package. Just use the right tools for what they were designed for.
If it means using multiple tools, fine.
The persons who said they used $SENDER in this example were either
lying or didn't understand the question.
