[Mailman-Users] Mountain Lion Server Issue after migration from Lion

Actually, I think this makes sense now.
Unless the sender is authenticated, I reject messages at the handshake if the addressee is not a local recipient. Local recipients include aliases.
I think the next directive is the key:
local_recipient_maps = proxy:unix:passwd.byname $alias_maps
My suspicion is that the addressee is evaluated in the above order (first, actual accounts, then aliases). In this flukey instance, because "mailman" is an actual system account, it is evaluated as such before postfix evaluates it as an alias to a listserver account. It then rejects it because it is a system account rather than a user account (uid falls below minimum allowed: 78 < 501). This is why mailman-request at ... works, but not mailman at ...
Accordingly, I don't think anything is actually wrong that warrants further digging. I only use the "mailman" list, which was set up by default, for testing. Any reason I can't delete it and make a "testing" list?
