See the threads with subject "dkim-signature headers" at

Executive summary:

Mailman currently removes DomainKey-Signature: and DKIM-Signature:
headers from posts and from mail to the -owner address. This is
probably not the right thing to do. Beginning in Mailman 2.1.10, the
removal of these headers will be controlled by a mm_cfg.py option with
the default being to not remove them.
