Comment (by strk):

 The help string for that variable:
 {{{
 # Some list posts and mail to the -owner address may contain DomainKey or
 # DomainKeys Identified Mail (DKIM) signature headers
 <http://www.dkim.org/>.
 # Various list transformations to the message such as adding a list header
 or
 # footer or scrubbing attachments or even reply-to munging can break these
 # signatures.  It is generally felt that these signatures have value, even
 if
 # broken and even if the outgoing message is resigned.  However, some
 sites
 # may wish to remove these headers.  Possible values and meanings are:
 # No, 0, False -> do not remove headers.
 # Yes, 1, True -> remove headers only if we are munging the from header
 due
 #                 to from_is_list or dmarc_moderation_action.
 # 2 -> always remove headers.
 # 3 -> always remove, rename and preserve original DKIM headers.
 REMOVE_DKIM_HEADERS = No
 }}}

 The current value (YES == 1) is not enough to fix lnicola's case above:
