Subject: [pmg-devel] [PATCH pmg-docs] pmg-mail-filter: clarify matching of Who objects
Date: Thu, 6 Feb 2025 16:16:20 +0100 [thread overview]
Message-ID: <20250206151620.32482-1-f.weber@proxmox.com> (raw)
In particular, explain that Who objects match against Envelope From
and Envelope To, not the From: and To: mail headers. This is
occasionally a source of confusion in enterprise support.

'Whitelist'. These are used in the default ruleset to globally block
or allow specific senders.
+Note that 'Who' objects match against the mail addresses given during the SMTP
