according to your previous master.cf, smtpd passes the mail to your
vacation "filter", so this happens before amavisd-new sees the message.
your script probably uses the sendmail command, so mail passes through:
postfix/smtpd (25) -> yourscript -> postfix/sendmail (pickup) ->
amavisd-new -> postfix/smtpd (10025).
