Are you following the FAQ at <http://wiki.list.org/x/ZoCj>? That is only
for very unusual situations.

The above appears to be the problem. The transport-mailman file is a
transport map, not a virtual alias map. the file referenced in
virtual_alias_maps should be virtual-mailman, but exactly how that plays
with your transport_maps is unclear.


What's in mm_cfg.py?

See <http://www.list.org/mailman-install/node12.html> for the
recommended way to to this without transport maps for Mailman.
