    Setup as follows:
    Exchange 2010 SP1. Send and Receive connectors are configured with the correct string (mail.company.com) on all containers.
    Last week contacted ISP and changed the A and PTR records (to match the above string) for public IP address.
    Still getting the same warning.
    I know I can live with it but just wondering why and what else I’ve missed?

    Thanks in advance
