I've got dovecot vacataion auto-responses working via sieve, but when the responses are sent, they are sent as if they are to be locally delivered, which causes them to bounce for domains that I am not local for. How can I get dovecot's sieve vacation response to check the domain is local or not?

Here is an example of what happens:

The LDA notices it needs to send a vacation response: 2019-05-14T10:50:47.827466-07:00 brant dovecot: lda(user@example.org)<14817><xL6LL/f/2lzhOQAAh856Uw>: sieve: msgid=<20190514135045.012486@localhost>: sent vacation response to <someone@somewhere.org>

but that response was sent via the postfix pipe through the dovecot lda transport... because that is local, and the domain it is sending to is not local, it bounces:

2019-05-14T10:50:47.923333-07:00 brant postfix/pipe[14821]: C998381539: to=<someone@somewhere.org>, relay=dovecot, delay=0.11, delays=0.04/0.01/0/0.06, dsn=5.1.1, status=bounced (user unknown)

Postfix is set to do this:

dovecot unix - n n - - pipe flags=DRhu user=mail argv=/usr/bin/spamc --connect-retries=1 -H -d 10.0.1.92 -s 10240000 -t 100 -u ${recipient} -e /usr/lib/dovecot/dovecot-lda -f ${sender} -d ${recipient}

require ["fileinto", "vacation"]; vacation :days 2 :subject "Helllo" "Hi";

Here is my doveconf -n:
