The problem is a bug in some versions of the Python email library. This
problem will occur whether the 'address' in *_these_nonmembers is a
regexp or a string. It also does not depend on the 'real name' being RFC
2047 encoded. All that is required is that the 'real name' be long
enough that the From: header folds into two lines. In this case, the
email.Utils function getaddresses() returns a spurious extra 'address'
based on the first line of the folded header and this is the 'address'
we check against *_these_nonmembers instead of checking the real address.

This bug exists in Mailman through 2.1.9. I will work around it for
Mailman 2.1.10.
