Looking in my daily bounced mails, i spotted this today from a customers server.
X-AntiAbuse: Primary Hostname - host.server.co.uk
X-AntiAbuse: Original Domain - customer.com
X-AntiAbuse: Originator/Caller UID/GID - [47 12] / [47 12]
X-AntiAbuse: Sender Address Domain - adomian.co.uk
X-Get-Message-Sender-Via: my.server.co.uk: authenticated_id: [email protected]
X-DNS-Warning: Reverse DNS lookup failed for host xxx.xxx.xxx.xx
X-HELO-Warning: Remote host xxx.xxx.xxx.xx incorrectly presented itself as my.server.co.uk
Received-SPF: pass (in6b.electric.net: domain of adomian.co.uk designates xxx.xxx.xxx.xx as permitted sender)
client-ip=xxx.xxx.xxx.xx; [email protected]; helo=host.server.co.uk;
So i ran 3 different RDNS tests from 3 different online engines and all 3 resolved the reverse dns to my server, using the same IP address as the one listed in those headers.
Any ideas ?
