Does setting from_is_list and / or dmarc_moderation_action to munge cause Mailman to do anything with existing DKIM-Signature headers? Will they be removed or left there?
The default behavior does nothing to DKIM related headers. This is from Defaults.py
# 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
