Plesk users can maliciously set up domains with names that are identical
to the domain names of popular online stores and other resources. For
example, they can use names such as gmail.com or paypal.com. Then, these
users can receive email messages sent by your customers to these domains
because the mail server ensures local delivery.
Plesk offers a pre-filled list of names of popular domains that are
already registered and belong to existing companies. If you turn on
checking for prohibited domain names, users will be unable to create
domains with the names from this list.
You can configure protection at Tools & Settings > Prohibited
Domain Names:
-
To switch on the protection, click Enable on the toolbar. Plesk
users will then be unable to create domains with the names from the
list. -
To add a domain to the list of prohibited domain names, click Add
Domain Name and specify the domain name that you want to prohibit. -
To edit a domain name in the list, click the name in the Domain
Name column of the list. -
To remove one or more domain names from the list, select these names
and click Remove.
