Currently, the automatic reply doesn't include the "References" header from= the original email. It often has an "In-Reply-To" header: ``` Message-ID: <cmu-sieve-392859-1781788754-1@hermes> Date: Thu, 18 Jun 2026 15:19:14 +0200 X-Sieve: CMU Sieve 3.0 X-Sieve-Action: vacation From: <[email protected]> To: <[email protected]> Subject: Received/Erhalten: Re: Received/Erhalten: Howdy! In-Reply-To: <46ce3dd0-2763-4f88-aca2-04ff30254ba4@ <mailto:46ce3dd0-2763-4= [email protected]>example.xyz> Auto-Submitted: auto-replied (vacation) MIME-Version: 1.0 ``` The "References" header would be great, so mail clients can better associat= e messages with conversations. Thunderbird, f.ex. does successfully show th= e first reply in the thread, but any further automatic replies are not in t= he thread anymore, because of the missing references. Would it be possible for the Cyrus Vacation module to properly generate the= "References" header according to RFC 5322 Section 3.6.4 (e.g., by appendin= g the original email's Message-ID to its existing References)? Are there any reasons why that wouldn't be possible? I read on this thread = <https://dovecot.org/mailman3/archives/list/[email protected]/thread/QDJB= 3R2DTIIDY3774BJRR64FURIMJ2CO/>, that Dovecot (apparently) does it. I am currently running Cyrus 3.4.3. I couldn't verify if this behavior has = already been changed in more recent versions up to 3.12. If it has, a quick= heads-up would be appreciated=E2=80=94otherwise, I would highly appreciate= this improvement.
