The cause for the problem can either be because that the MX record for the domain zone of destination recipient.To solve the issue, first check if the domain MX record and its priorities to verify that it’s pointing to the correct mail server . If MX record is correct, ensure that the destination domain is properly designated. which means if the mail is resolving from our server then its entry should be in /etc/localdomains and Local Mail Exchanger should be selected form Main >> DNS Functions >> Edit DNS Zone and if client is using any remote mail server then the domain entry should be removed form /etc/localdomains and added under /etc/remotedomains and select Remote Mail Exchanger from Main >> DNS Functions >> Edit DNS Zone
