MX record and Mail server
Posted on 2011-09-16
We have outsourced our mail services to the service provider. The service provider has configured the linux box in our LAN for fetching the messages from their data center. In the MX record IP given is, one of the IP which has been configured in our router/firewall in turn this is natted to the linux box in the LAN.
We have changed the ISP due to this new IP pool is allocated to us now I have below doubts
1.Is it required to inform the mail service provider of this changes is there any thing that they will have to do, what I am thinking is change the IP address to the new IP address and configure this new IP pool in the router/firewall.
2.Request you to please help me in the measures or best practice steps to be followed.
3.We will still continue to use the mail services from the mail service provider only change in the IP pool due to the ISP change
Please help step by step.
Thanks in advance.
