Postfix is not forwarding emails from domains hosted on the same server
Hello, recently we started facing an issue. We are using Postfix and Dovecot on Centos.
If i send an email to a domain hosted on the same server(@domain1 –> @domain2 both hosted on the same server), forward does not work.
If i send an email from a domain hosted on our server to an email at the same domain(@domain1 –> @domain1), forward works.
If i send an email from an external domain forward also works.
Could anyone be of any help? I cannot figure it out for the past few hours.
