With your configuration, the vacation script is responsible for the
final delivery decision. If that script only executes the vacation
command, the message is stored into INBOX by default (implicit keep).

If you want to force execution of the vacation rule, it should be in
sieve_before (or in you case that would be sieve_before2).

As a bonus, the user's main active script (filters.sieve) will have
responsibility for the final delivery. So if there's no (implicit) keep,
there will be no message in INBOX.
