Not OT at all. I saw one person suggested procmail which will do the job. 
I prefer doing it a different way. Use the access databse in sendmail. 
Assuming your kid's name is elmo, and you wanted him to be allowed email 
from three different addresses, 

To: elmo at obrien-pifer.com	REJECT
From: kid1 at d1.com		OK
From: kid2 at d2.com		OK
From: kid3 at d3.com		OK

The advantage is that the mail will be rejected by sendmail before 
reception completes. The disadvantage is that you need to do a bit more 
reading to fully understand it. ;-)
