This script will check each MX entry for every domain configured on this machine. 

The MX record will be determined from the zone file associated with this server, 
not from a remote query of the DNS record. If you are using and editing the zone
file on a server not associated with this server through a DNS cluster configuration,
then this utility will configure your email settings incorrectly. 

This utility updates the following files which alter the local delivery and sending
methods of email:

/etc/localdomains
/etc/remotedomains
/etc/secondarymx

As a safety precaution you must run this utility with the argument "--yes" to proceed.
    example: 
        $0 --yes
EOM
    exit;
