Just construct your own Message-Id header, including $local_part, then
replace original header with headers_add/headers_remove (in routers)
or add_header/remove_header (in ACLs). Some marker string, including
$local_part, may be safely join (left) to the original message-id.
But take into account that message-ids, listed in References and
In-Reply-To headers of outgoing mails, are hooks for building threads.
So alternating Message-Id header for incoming mail you could mark reply,
but may occationaly break representaion of threads for the recipients.
