I came back from a few days out of town to find 1000s of frozen queue entries and my server blacklisted by gmail. Here's a sample:
: mailq | head -20 6d 1.3K 1nKNYR-000bDv-0w <[email protected]> *** frozen *** D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] D [email protected] [email protected] D [email protected] D [email protected] And here's what that item looks like in detail: : exim4 -Mvc 1nKNYR-000bDv-0w|head -20 Received: from [103.104.169.173] (helo=ogcb16c7f19.openstacklocal) by home.hst.name with esmtp (Exim 4.94.2) (envelope-from <[email protected]>) id 1nKNYR-000bDv-0w; Wed, 16 Feb 2022 16:53:23 +0000 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Content-Description: Mail message body Subject: From The Commissioner Debt Management Service To: Recipients <[email protected]> From: "Mr. Timothy Gribben" <[email protected]> Date: Thu, 17 Feb 2022 00:53:15 +0800 Reply-To: [email protected] ... I don't have open relaying set up, at least I don't think so, and a few online checkers agree... How is this happening/where are the recipients coming from? More importantly, how do I fix my exim4 configuration to stop this! Thanks for any help, ht -- Henry S.
