[Mediawiki-l] Possible to block users from using a specific email service?

[Clayton]

I'm busy tidying up spam on the OOoWiki on a fairly regular basis.  The 
OOoWiki uses several tools to block/stop spammers (BadBehavior, the spam 
RegEx etc.)... it's working most of the time, but the spammers still get 
in and vandalize pages several times per week.  I've been poking around 
and discovered that a lot of the spammers (who create an account just to 
post a URL link) are using Mailinator dot com to create a one-time-use 
throwaway email address to receive the Wiki user authentication email.

Is there any practical way of blocking new users from using specific 
services like Mailinator?  Is there a better way of dealing with 
situations like this?
