Verified.  Thanks for the recipe, it was crucial to me finding the
bug.  Unfortunately, I don't have time just now to fix it, but it
shouldn't be difficult.  The problem is that addrs in the password
dictionary are kept case-preserved, but the match is done

The second one ought to be refused as already subscribed.  And the
reason all this extra cruft was put in place was because there really
are some domains that differentiate based on the case of the username
part.  Thus in these domains, if I subscribed with BWARSAW at crufty.com, 
but Mailman insisted on sending the mail to bwarsaw at crufty.com, it
would bounce.
