(See Section 5, especially Section 5.2.) This is not required by the RFC just recommended. That said it is indeed a tricky issue ... I'm just saying the mail list server is not guilt free here. That said I am not sure what mailling list server options there are regardning DKIM. The receiving server probably should not be emailing the DKIM author's postmaster either - so that is a no-no as well - it should just reject or accept message and not creating more spam. gene [0] http://tools.ietf.org/html/rfc6377 [1] MLM = mailing list manager.
