Comments allowed domains control

Enable only for non logged in (guest) users - Decide if to apply the comment restriction only to non logged-in (guest) users or to both logged-in and non logged-in users.

Use allowed domains for comments filtration - Enable this option to filter who is allowed to leave comments on your site.
Use below whitelist domains for filtration - If enabled, only domains which are added in the Domains that are allowed to leave comments area will be allowed to leave comments. Note: this option was introduced in version 1.6.5.
Domain is not allowed to left a comment - You can change the message that the guest will see, if he is not allowed to leave a comment.

Domains that are allowed to leave comments

Add new domain or domain extension - Enter here domains that you want to be allowed to leave comments.

You can use full domain names (e.g. gmail.com) or wildcards (e.g. *mail.com). You can also use domain extension names with wildcards (e.g. *.com).

Note: this feature doesn't affect leaving comments for registered users. If the user is registered on the site, it doesn't matter if he is logged-in or not. If he is logged-in, his comments will be published, and if he is not logged-in and tries to leave a comment using his email (that was used for registration on the site) - the comment will be published.
