+ incompatible with common list features such as footers, causing
+ participating email services to bounce list traffic merely
+ because of the address in the From: field. <b>This has resulted
+ in members being unsubscribed despite being perfectly able to
+ receive mail.</b>

+ The following actions are applied to all list messages when

+ <dd>Do nothing special. This is appropriate for anonymous lists.
+ It is appropriate for dedicated announcement lists, unless the
+ From: address of authorized posters might be in a domain with a
+ DMARC or similar policy. It is also appropriate if you choose to
+ use dmarc_moderation_action other than Accept for this list.</dd>
+ <dt>Munge From</dt>
+ <dd>This action replaces the poster's address in the From: header
+ with the list's posting address and adds the poster's address to
+ the addresses in the original Reply-To: header.</dd>
+ <dt>Wrap Message</dt>
+ <dd>Just wrap the message in an outer message with the From:
+ header containing the list's posting address and with the original
+ From: address added to the addresses in the original Reply-To:
+ header and with Content-Type: message/rfc822. This is effectively
+ a one message MIME format digest.</dd>
+ </dl>
+ <p>The transformations for anonymous_list are applied before
+ any of these actions. It is not useful to apply actions other
+ than No to an anonymous list, and if you do so, the result may
+ be surprising.
+ <p>The Reply-To: header munging actions below interact with these
+ actions as follows:
+ <p> first_strip_reply_to = Yes will remove all the incoming
+ Reply-To: addresses but will still add the poster's address to
+ Reply-To: for all three settings of reply_goes_to_list which
+ respectively will result in just the poster's address, the
+ poster's address and the list posting address or the poster's
+ address and the explicit reply_to_address in the outgoing
+ Reply-To: header. If first_strip_reply_to = No the poster's
+ address in the original From: header, if not already included in
+ the Reply-To:, will be added to any existing Reply-To:
+ address(es).
+ <p>These actions, whether selected here or via <a
+ href="?VARHELP=privacy/sender/dmarc_moderation_action">
+ dmarc_moderation_action</a>, do not apply to messages in digests
+ or archives or sent to usenet via the Mail<->News gateways.
+ <p>If <a
href="?VARHELP=privacy/sender/dmarc_moderation_action">
dmarc_moderation_action</a> applies to this message with an
action other than Accept, that action rather than this is
