    Problem with IP repution using email security (mxlogic)

    jffrybauer

      Hello,

       

      This is my first post, so hopefully this is the right forum.

       

      My company is a McAfee email security (mxlogic) customer.  We have recently made a change to our email system and have a new last hop MTA with new public IP (we do not use mxlogic for outbound filtering).  Our previous last hop MTA mail server is listed in trustedsource.org with a good reputation.  Our new IP is listed with a bad reputation.  Both addresses are in the same subnet.

       

      We are currently unable to deliver mail to any other mxlogic customers.  We get the standard 554 Denied NDRs.  I don't see any DNS record issues, and per mxtoolbox we are not listed on any blacklists.  I've been submitting samples to saas_falsepositives@mcafeesaas.com for the last two days and am still not able to send to anyone who uses mxlogic for inbound filtering.

       

      Is there anything else I can do with McAfee support to get our IP address removed from whatever mxlogic blacklist it is on?

       

      Our new server hostname and IP are:

      zixout001.halfpenny.com

      68.168.93.90

       

      Thanks in advance.
