SMTP and POP3 services have been properly installed. Now I will send my own email and send an email out of the outside. It is unable to receive the outside email. After: http://www.dnsstuff.com and http://www.dnsreport.com Test returns the following information: [COULD NOT CONNECT: GOT AN UNKNOWN MAIL from Response: 530 5.7.3 Client Was Not Authenticated is really strange. My DNS resolution did not find problems. And DNSMX records have taken into effect tomorrow to see SMTP configuration.
