Sendmail fails receiving mail since the IP changed on Redhat Server

Linux and Unix-Like Red Hat
1

Hi,

Since i move my Linux Redhat server on another Network with new IP address. WE'RE ABLE TO SEND MAIL OUTSIDE BUT we can not receive any incoming mail. It alway points to the old IP. I updated new IP in /etc/hosts and /etc/sysconfig/network then reboot the system. 10.117.32.20 is an old ip and server3 is the hostname and we use the same hostname on new machine.

Here is the errors that i'm getting form SMPT to my inbox:

Have you changed MX also pointing to new IP ... also check from other places if MX is reflected

Hi,

No, where to change this file?

Humm, this is a cached answer and not an authoritative answer (no aa flag). Maybe the change has not yet propogated for some reason.

You need to talk to whoever manages the DNS records for AGR.GC.CA
