====I have two mail servers on one internet connection. They are using different Static IP's.
Recently, I began getting this error for any emails that I attempt to send from domain B (iredmail) to domain A (exchange).
I can't send the other way, but exchange is not showing any errors.
I have updated both the main hosts and resolv.conf as well as the ones in /var/spool/postfix/etc
Do you have any other advice?
