Allow me to bump this thread. I believe there is a bug somewhere. Either in the code, or in the documentation.

Hello there,
When using the doveadm command (search HEADER "X-Discourse-Post-Id" "") or the IMAP command (SEARCH HEADER X-Discourse-Post-Id ""), emails containing a X-Discourse-Post-Id header are not listed.
I've also tried with non X- headers, such as List-Unsubscribe and Auto-Submitted.
RFC 3501 1 and Dovecot's documentation 2 both says that this command should return emails containing the header searched.
I couldn't find a mention of this bug in the git history, hence why I'm posting here, maybe there is something wrong with my installation ?
I'm running Dovecot 2.3.20 on Debian on amd64 with an ext4 filesystem. I attached the output of dovecot -n.
