NAME

       Sympa::Spindle::TransformOutgoing - Process to transform messages - second stage

DESCRIPTION

       This class executes the second stage of message transformation to be sent through the
       list. This stage is put after storing messages into archive spool (See also
       Sympa::Spindle::DistributeMessage).  Transformation processes by this class are done in
       the following order:

       •   Executes "post_archive" hook of message hooks if available.

       •   Adds / modifies "Reply-To" header field, if "reply_to_header" list option is enabled.

       •   Adds / overwrites following header fields:

           "X-Loop"
           "X-Sequence"
           "Errors-To"
           "Precedence"
           "Sender"
           "X-no-archive"
       •   Adds header fields specified by "custom_header" list configuration parameter, if any.

       •   Adds RFC 2919 "List-Id" field, RFC 2369 fields (according to "rfc2369_header_fields"
           list configuration option) and RFC 5064 "Archived-At" field (if archiving is enabled).

       •   Removes header fields specified by "remove_outgoing_headers" list configuration
           parameter, if any.

       Then this class passes the message to the last stage of transformation,
       Sympa::Spindle::ToList.

CAVEAT

       •   Transformation by this class can break integrity of DKIM signature, because some
           header fields may be removed according to "remove_outgoing_headers" list configuration
           parameter.
