I'm currently having an issue with Zimbra, so any help is appreciated. I set Zimbra up on a test machine to where it sent email flawlessly to outside accounts. After testing I went to move it to our Data Center and had to change the IP of the machine. Now it is not sending emails, it's giving me the message "Message not sent; one or more addresses were rejected. Rejected addresses: firstname.lastname@example.org"
When I first encountered this message, I corrected it by using Split-DNS. Is there something else I need to change after moving the server?
What I've done:
Changed the machine's IP and gateway and changed HOST file.
Changed DNS entry on our internal DNS server to point to the new IP.
Changed the IP in mydomain.com.zone.
BIND 9.3.3 w/chroot
Again, any help would be greatly appreciated. Thanks.
