I've seen a similar system, but it wasn't majordomo.

All they had to do was reply to the message with the word  OK

If they had a weird system and couldn't reply to the message but had to 
send another message or something, they could reply with   OK <validation-code>

and thus the system knew it was them....

The system I used was  listserv@taunivm.tau.ac.il
