Hi all,

I'm migrating a server with older postfix & older mailman2 and noticed one setting in postfix's main.cf:

owner_request_special = no

The postfix docs for this setting say:

"Enable special treatment for owner-listname entries in the aliases(5) file, and don't split owner-listname and listname-request address localparts when the recipient_delimiter is set to "-". This feature is useful for mailing lists."

Which I don't really grok.  I'm not sure why it's set to `no` on the older server.

It's set to `no` because `yes` is the default and the appropriate setting for MM 2.1 is `no` except it shouldn't matter because owner-listname is not a MM 2.1 address and while listname-request is, in a MM 2.1 installation recipient_delimiter is normally set to `+`.
