Invalid email addresses looping

We've been using the QtmmSendMail API wrapped up in Dave Leland's SNDEMAIL
command for quite a long time and have been happy with it.

This last weekend we put on cume's, hiper's, etc on.

Now when we execute the following command:
SNDEMAIL ADDRESSEE((GOODADDRESS@DEKKO.COM)
                   (BADADDRESS@DEKKO.COM))
         SENDER(INVALIDADDRESS@DEKKO.COM)
         SUBJECT(TEST)
         MESSAGE('This is a test')

The mail will successfully arrive at the good address.  However the
log.nsf, mail routing events, will have multiple entries in there for
attempts to send back to the sender, and the sender is bad.  Infinite
loop.  On a 12way each processor is 8.333% of cpu.  The ROUTER job on this
Domino partition is eating 17% of cpu.  And the log.nsf is growing by
2GB/day!

I have an incident (1491570) opened on this.  However I need to let them
know I can duplicate this loop and how.  I wish the passport advantage web
site was up enough that I could type this little tidbit in but the
sucker's been down now for a few days.
