The state for this feature seems to survive a dovecot restart, so it must be persistent somewhere and not just stored in RAM.  But I don’t recall configuring any place where that state would reside.

There is a file called .dovecot-lda.dupes. It's documented in https://doc.dovecot.org/configuration_manual/sieve/usage/#sieve-usage-vacation-auto-reply
