“The entered e-mail domain has no valid MX record.”
That is something wroten as an error report on my phpBB3. I use XAMPP, as my webserver. Its easy to install and easy to manage.
I install it ad localhost, so I don’t need any email confirmation. As a new member I use form registration, later I submit it. Error prompted as Title above.
Then I got a good answer from this site, they solve it.
here some note:
Cause
phpBB3 by default checks the MX record of all entered email addresses during registration to make sure the email domain is valid. If the domain does not have a valid MX record this error is generated.
Solution
Go to the,
Admin control panel -> general tab -> Server configuration -> security
Then for the option
Check e-mail domain for valid MX record:
If enabled, the e-mail domain provided on registration and profile changes is checked for a valid MX record.
select the 'no' checkbox
