I installed a new exchange server for a new domain called TI.local. Server name: MAIL
Configured firewall to point SMTP to new server IP: 192.168.1.5
our domain is taraink.com
I can send but not receive mail.
220.127.116.11 does not like recipient.
Remote host said: 550 5.7.1 Unable to relay for firstname.lastname@example.org Giving up on 18.104.22.168.
