There is no need for mailman/MLM to duplicate the functionality already provided by other DKIM-signing solutions (like amavisd or opendkim milter), all that is needed it to configure mailman fanout to be fed back to the signer. > after remove my own There is no need for a MLM to remove original signatures (except to save some bytes in transmission and storage), even if it knows it will make changes which will invalidate them. A failed signature is equivalent to no signature. > this is only possible if body is not modified, but i know dkim works in > postfix maillist but fails masurable other places > > problem for me no :) It is only a problem if your domain claims that mail with no valid author-domain signature is to be discarded. Such claim can be done through publishing an ADSP policy record in DNS (RFC 5617). It is only appropriate to publish a 'discardable' policy for domains which always send direct mail (never through foreign mailing lists), such as paypal, ebay, banks, etc. Domains which have regular users which post to mailing lists, should not publish a 'discardable' policy.
