Hi all,

When I use www.dnsreport.com to test my email account, I get this report

Trying to connect to all mailservers:

domain.com. - 216.x.x.x [Could not connect: Got an unknown RCPT TO response: 550-test.dnsstuff.com (test.DNSreport.com) [66.36.241.109] is currently not
550-permitted to relay through this server. Perhaps you have not logged into
550-the pop/imap server in the last 30 minutes or do not have SMTP
550 Authentication turned on in your email client.
]


How to fix this error?

Thanks
