1. You could add a header in "another router" and test for it in the
vacation router.
2. You could test for the presence of "$local_part@$domain" in the To:
header and make that a condition of your vacation router. Something
like:
condition = ${if match{$h_to:}{${rxquote:$local_part@$domain}}}

Ah, sorry, that's a misunderstanding. In this context, "delivery" means
"a process that is trying to deliver the message". The value of
"first_delivery" becomes FALSE only if there are delays in delivering to
some of the recipients, and a message has to wait on the queue and be
tried again later.

A router processes an address, not a message. An operating system
process runs an Exim delivery process, which makes a "delivery attempt"
on a message - this involves tryint to deliver to all the as-yet-
undelivered addresses.
