Features
This plugin will verify for disposable email addresses when a user tries to use them. It makes use of several online services which provide this validation, you need to sign up with at least one of them.
The following online services are supported:
You can use multiple services. When an email needs to be verified it will pick a random one from the list until a services responds that the email domain is either a disposable one, or not. If there are no available or working services the domain will be accepted.
Verification is only one after the after the standard email verification of Discourse have passed. So domains already added to the blocked_email_domains setting takes precedence.
Some of the supported services have quite acceptable free tiers. So for a small forum is will probably not cost you anything.
The result of a verification is cached for a while.
The actual email addresses used by users are not send to the services, the local part will be replaced by “example”. So if the users enters “my-name@some-domain.test” then a check is performed on “example@some-domain.test”.
