[Mailman-Users] mailman 2.1.10 .. yahoo says "domainkeys=fail (badsig)" ...

[Bob001]

ah...i see. Thanks Jim for clarification.

So, how you all are exactly achieving post-signing of messages after
REMOVE_DKIM_HEADERS=Yes? 

Any suggestions?

We are on postfix and dkimproxy with mailman.

Do we have any documentation on what changes should be done on
postfix/dkimproxy side for post-signing?

- Regards,
Bob.
