      Hello Team,

       

      I am an email administrator and I found the emails from our servers to multiple recipients are getting rejected.Opened a ticket with DynDNS almost 10 days back but didn't receive any updated.Ticket number for reference - Case: 01172287. Can someone please help into this case all email rejection errors are referring to use DynDNS.Seems to be our servers are some reason blacklisted at DYNDns.

       

      Error we see in the DFR - Recipient address rejected: Mail appeared to be SPAM or forged. Ask yo...S-Administrator to correct HELO and DNS MX settings or to get removed from DNSBLs; Please use DynDNS, stat=User unknown
