Hello, my email was flagged as spam by Microsoft.
I have the received email, together with all the headers that Microsoft added. Specifically the item: X-Microsoft-Antispam-Message-Info: I have found a tool on github, which attempts to decode this convoluted item (https://github.com/mgeeky/decode-spam-headers) And one of the decoded lines says: (58800400005) - (GUESSING) Somehow related to First Hop server reputation, it's reverse-PTR resolution or domain impersonation I am using header rewrite to hide my own IP address, and use localhost [127.0.0.1] instead. So that the first hop looks like this: Received: from [127.0.0.1] (localhost [127.0.0.1]) by mail.xxx.yyy (Postfix) with ESMTPSA id 7E011B0 for <a...@bbb.com>; Wed, 9 Aug 2023 07:04:42 +0200 (CEST) is this considered bad practice? Or why am I being penalized for this? All I am trying to achieve is not to disclose from where I am sending my emails thanks, _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
