You might need this plugin: http://wordpress.org/extend/plugins/no-disposable-email/

You can hook into the register_post action hook, and pass the email address through is_email(), to which you can add a filter to disallow the characters (such as "+" used to create disposable email addresses).

please also have a look at http://wordpress.org/extend/plugins/block-disposable-email-addresses/ which is a plugin for wordpress that uses http://www.block-disposable-email.com/

Thought I would add to this answer as none was specified and it took me a while to find a solution.

What I am using is the blacklist method where you specify a list to block. It works well as users just give up after trying the biggest disposable email providers.

The code can be found here: How to Block Disposable Email Addresses: PHP Code

It works by letting you create an array of domains you which to block. You then provide an email address as a variable and this gets split to get the domain. This is compared to the list and as you can see on the website you can do whatever you like if a disposable email is detected.

Good luck!
