The Postfix mailing list is "friendly" already. It does not break DKIM since it does neither mess with From nor add junk to Subject or the message bodies. Besides, all messages on this list contain the correct List-FOO headers. As for spam, messages on the Postfix mailing list usually score with deep negative values in SpamAssassin. You're barking up the wrong tree here. ;-) -Ralph
