From bcdcb181ee1cd5e90c889eb09192e1fae8b5e6b0 Mon Sep 17 00:00:00 2001 From: Gabriel Goller Date: Fri, 8 Sep 2023 15:06:57 +0200 Subject: [PATCH] fix #4162: sys: 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.
