As I understand, AcceptableAliases are defined as regular expressions,
what if Mailman put the values that are a valid list name to
transport_maps? Converting regex to a listname doesn't sound like a
straight forward thing to me though.

This most definitely adds some complexity for unique checks of
Listnames. I am not sure if we already check acceptable alias rules for
existing mailing lists to make sure they don't match any new list
created. We'd have to do it if we start putting acceptable aliases in
transport maps.

As a feature, it could be helpful to have multiple posting addresses for
a single List. Are there any major downsides to doing this?
