Subject: [pmg-devel] [PATCH pmg-api 6/7] reinject_local_mail: sign mails with DKIM based on header
Date: Tue, 25 Feb 2025 00:24:51 +0100 [thread overview]
Message-ID: <20250224232451.399803-7-s.ivanov@proxmox.com> (raw)
In-Reply-To: <20250224232451.399803-1-s.ivanov@proxmox.com>
as most mails PMG generates locally has an empty envelope-sender,
signing only makes sense when the from-header domain is used as
signing domain.
This fixes #3423, and partially addresses #2971 and #4658 (bounces
generated by postfix directly are not passed through our stack, and
should not be processed in general - see
https://www.postfix.org/postconf.5.html#internal_mail_filter_classes).
