I guess that depends on what you call a configuration option.

You could put this in mm_cfg.py

GLOBAL_PIPELINE.remove('AvoidDuplicates')

That would just remove the Handler so every list member that is a direct
recipient would receive both the list and the direct copy regardless of
her avoid duplicates setting, or you could apply the attached patch to
Mailman/Handlers/AvoidDuplicates.py, or you could patch the module but
name the patched module say Mailman/Handlers/MyAvoidDuplicates.py and put

GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('AvoidDuplicates'),
'MyAvoidDuplicates')
GLOBAL_PIPELINE.remove('AvoidDuplicates')

im mm_cfg.py. See the FAQ at <http://wiki.list.org/x/l4A9>. Note: the
first line is wrapped but it doesn't matter because of Python's implies
continuation inside parens. Also note that this latter method is
preferable to simple patching AvoidDuplicates.py for reasons mentioned
in the FAQ.
