No, they attempt to block similar domains. And completely fail at it.

I never use my main email for anything I don't feel requires it, and while maininator.com is often blocked, I've never in my life had to refresh the mailinator page more than twice for an alternate domain that works. Since mailinator accepts email from any domain that has it's MX record set to it, if you own a domain you can set it to be an alternate name to mailinator in seconds. Enough people have done this.

There are tons of lists that are regularly updated that list all published mailinator.com domains. While it's true you can set up a new one on a subdomain of your own, as soon as you publish it to mailinator and it enters the rotation of the domains that come up, it's easily added to the lists and blocked. There's even a commercial live list with plugins for most email systems that blocks on any of the hundreds of mailinator-listed domains as well as over a thousand other disposable email domains.

Heck you can just write a script to refresh the mailinator.com homepage to start pulling out domains to block: @veryrealemail.com, @chammy.info, @mailinator2.com, @spamthisplease.com, @sogetthis.com, @mailinator.net, @binkmail.com, @sendspamhere.com, @spamherelots.com, etc.

No, it's actually super easy to block it if you're clever enough ;)

Could you point me to a site that does successfully block it?
