[Exim] add header when rewritten

Hello,

is it possible to add some "x-" header to mail message when
SMTP-time rewriting has occured?

I mean
------------
begin rewrite
\N^(.*?)@domain$\N "$1@otherdomain"+'header_add=x-local-rewrite: true' S
------------

Or any other way to indicate to transport_filter -program that
inbound message address was rewritten. (Command line or email content
possible)

best regards, Jori
