From a992ba134c8ef83cc7e405bf616f3010c1718f73 Mon Sep 17 00:00:00 2001 From: Gabriel Goller Date: Tue, 19 Sep 2023 09:35:25 +0200 Subject: [PATCH] fix #4162: added `Auto-Submitted` header to email body `Auto-Submitted` is defined in the rfc 5436 [1] and describes how an automatic response (f.e. ooo replies, etc.) should behave on the emails. When using `Auto-Submitted: auto-generated` (or any value other than `none`) automatic replies won't be triggered.
