There is a domain:
And its subdomain:
When I send mail to
email@example.com - it is ok, works. But when I send mail to
firstname.lastname@example.org - it gives error:
error while sending email: The following addresses had permanent fatal errors, reason: 550 email@example.com recipient unknown
IP address of mail server is same for domain and subdomain.
How could I write dns record for its subdomain?
My current records for this domain are these:
example.gov.en. IN A 192.168.1.1 example.gov.en. IN MX 10 example.gov.en.
