550 Host detected by Reverse DNS

    Reverse DNS lookup for your IP address is failing.  Axcess does require that all connecting Mail Transfer Agents have established Reverse DNS.


    Reverse DNS is a way of associating an IP address with its domain name.  The reverse DNS identifier is contained in the PTR portion of the IP Zone file.

    If you are on a dynamic IP address, please call your ISP and request a static IP address with proper reverse DNS before attempting to send mail to Axcess through that server.

    If you are on a static IP address, please call your ISP or DNS provider and ask them to establish a reverse DNS record for your IP address reflecting your correct domain name.
