I suspect the problem is in Python's rfc822 module:

>>> a = rfc822.AddrlistClass('David E.Fox <dfox@m206-157.dsl.tsoft.com>')
>>> a.getaddrlist()
[('', 'DavidE.Fox'), ('', 'dfox@m206-157.dsl.tsoft.com')]

Mailman, interestingly enough, has Utils.ParseAddrs() which appears to
try to work around problems in rfc822:

>>> ParseAddrs('David E.Fox <dfox@m206-157.dsl.tsoft.com>')
'dfox@m206-157.dsl.tsoft.com'

which seems to suck out the right address in this case.  What should
probably in MM2.1 is for MailList.HasExplicitDest() to fallback on the
output of ParseAddrs() if the rfc822 method doesn't match.
