What is the Domain Names for Email Address Validation option when creating a new member?

If set, against a member you will be able to record valid domain names for the main email address recorded against a person on that membership. It will warn in MEMNET administration but the validation is enforced in Member Self Service.

Note: You can use '*' wildcard for Top Level Domain and Country Code to allow all possible combinations (e.g memnet.com.* or memnet.*.*).

To enable this setting, you need to go to Administration then click on Company Settings, now scroll down towards the bottom of the page and make sure the 'Enable Domain Names Validation of Email addresses' is ticked.
