I have to configure MX record configuration on GTM....I have searched the solution a lot but have not found it in askf5.com.   Having bought GTM, our customer wanted their service provider to stop...

    You can configure an MX record within the appropriate zone in ZoneRunner and specify the target as the desired hostname of mail.messaging.microsoft.com.

Thanks Cory...

What will be the zone type...

Actually, I need a bit more detailed help, I will appreciate if you can help me with a little procedure...

And, why do I see 127.0.0.1 in my named.conf file...

named.conf

restrict rndc access to local machines use the key in the default place: /config/rndc.key

controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; }; };

logging { channel logfile { syslog daemon; severity error; print-category yes; print-severity yes; print-time yes; }; category default { logfile; }; category config { logfile; }; category notify { logfile; }; };

options { listen-on port 53 { 127.0.0.1; "zrd-acl-000-000"; }; listen-on-v6 port 53 { ::1; }; recursion no; directory "/config/namedb"; allow-transfer { localhost; }; check-names master warn;

check-integrity yes;
max-journal-size 1M;
forwarders {
    172.31.171.11;
    172.31.201.11;
    172.31.201.12;
};

};

acl "zrd-acl-000-000" { 127.10.0.0; };

server 172.31.171.11 { }; server 172.31.201.11 { }; server 172.31.201.12 { };

    You'll need to create a master zone for whatever your domain is, customer.com in your example. So within your customer.com master zone, you'll define an MX record. In the record configuration, your "Name" field will be "customer.com.". Your "Mail Server" field will be "mail.messaging.microsoft.com.". The TTL you set is up to you, but would recommend either 1800 or 3600. Preference value shouldn't matter. When your service provider defers resolution to your GTM for the customer.com zone, you'll now be configured to respond back to MX record queries for customer.com. Your original question mentions moving A records. Has this already been done, and if so, how are you providing authority for these records?
