This plugin prevents people from registering with disposable email addresses (dea) like the ones provided by mailinator (also known as throw-away email, one-time email). It protects your most important asset, your registered user base, by preventing contamination by fake accounts. This plugin working principle is similar to spam blacklists.
It hooks in the wordpress function is_email() so it will extend the known email validation of wordpress to detect dea domains.
The plugin itself does not contain a list of domains to block. Instead of local maintenance the plugin uses the service of http://www.block-disposable-email.com. This is a very accurate free service for up to 200 queries a month. For huge sites several commercial plans are available.
Please see the FAQ section for some more information.

The Temp Mail Detector WordPress Plugin is a privacy first temporary email prevention plugin which helps stop disposable emails from being able to sign up or comment on your website.
By combining the ability to use custom block lists alongside the optional Temp Mail Detector API you can choose which hosts are allowed or not allowed to register or comment on your website.
<h3>What’s available</h3>
This plugin offers multiple options: 
* Blocklist – You can enter a list of domains you would like to block at signup. 
* Protect comments – Choose if you would like the plugin to protect comments from disposable emails. 
* Plus emails – Block emails which have a <code>+</code> in the user part. 
* External check – This makes use of the dynamic Temp Mail Detector API for real-time checks.
To check against the Temp Mail Detector API, you will need to <a href="https://tempmaildetector.com" rel="nofollow ugc">register for a free API key</a>. 
Each API key gets 200 lookups for free each month, which reset on the first of the month.
<h3>External services</h3>
If external checks are enabled via the use of an API key, when checking if an email is temporary or not through the Temp Mail Detector API, only the website address of the email is sent to be analysed. Your users emails addresses are never transmitted or shared with anyone.
If an email is <code>user@website.com</code>, this plugin will only send <code>website.com</code> to be analysed. By never sharing your users emails, you can both check if an email is disposable while also maintaining your users privacy.
