Hmm, if you use stream_by_domain() already, all recipients should have the 
same domain already.

The man of stream_by_domain() says:

"
stream_by_domain() looks at all the recipients of  the  message,
               and  if  they  belong  to the same domain (e.g., 
joe at domain.com,
               jane at domain.com and sue at domain.com), it returns 0 and  sets 
the
               global  variable $Domain to the domain (domain.com in this 
exam‐
               ple.)
"

- ->

if($Domain =~ /\A(?:domain1|domain2|...)\z/i) {
 	#action_delete_all_headers('X-Orig-Rcpts'); # see below
 	action_add_header('X-Orig-Rcpts', join(', ', @Recipients));
}

BTW: If someone knows your mail setup or you forward such mails around, 
the header may contain more (or not) what you intend. Depending on your 
needs you should replace the 'X-Orig-Rcpts' header.
