Here are the headers of an email that I believe should have triggered
an auto-reply but didn't (with email addresses and names masked for
privacy). I don't see any headers here that should prevent vacation
from auto-replying.

Yes - that is indeed unfortunate; it makes it just about impossible to
debug. If I was using the dovecot sieve plugin would that have better
logging so I could find out what's going on?
