The @mailinator.com addresses are frequently banned, but not the stockpile of aliases, e.g. @notmailinator.com.

It's trivial to setup your own mailinator with a custom domain or subdomain -- http://mailinator.blogspot.fr/2008/01/your-own-private-maili...

I use mailgun for that - it's easy to set up a catch-all on some unused domain to forward to your email address. Free for <10,000 mails per month.

You can just point your own domain at their mx.
