What is the policy to resolve this issue? Turning off DKIM isn't an option. If there is a signature, such as someone in the chain coming through gmail, it must validate or the message is rejected. I understand this is a common problem for email lists and there are patches available to reformat messages. http://tools.ietf.org/html/rfc6377 The best general recommendation for dealing with MLMs is that the MLM or an MTA in the MLM's domain apply its own DKIM signature to each message it forwards and that assessors on the receiving end consider the MLM's domain signature in making their assessments. (See Section 5, especially Section 5.2.)
