I presume you mean "NFS" when you say "NIS"? If not, I'm very confused!

I think we are talking at cross purposes here. There won't be any
"nobody" address involved in what I (thought I) suggested. My idea was
that the slave should do normal delivery, and also send the message to
the master. Always. So on the slave you might have a director like this
as the first director:

xxxx:
driver = smartuser
headers_add = X-Something
new_address = $local_part@$domain : $local_part@MASTER.$domain
new_director = the-name-of-the-next-director

with some special routing that sends MASTER.$domain to the master
server. Then, on the master server, you rewrite MASTER.$domain to
$domain, let the address run through the directors that do the vacation
stuff - you should be processing a message that is identical (apart from
an extra received: header) to one that comes directly - but before your
final delivery director, you put

xxxx:
driver = smartuser
condition = ${if eq {$h_X-Something:}{}{no}{yes}}
new_address = :blackhole:

in order to bypass the delivery.

Of course, this puts extra work on your master. If you can arrange for
the slave to know when not to bother (the user is not on vacation) you
can save some work.
