+7/27/16 - Converted all domains to the second level. This means that starting from [this commit](https://github.com/martenson/disposable-email-domains/commit/61ae67aacdab0b19098de2e13069d7c35b74017a) the implementers should take care of matching the second level domain names properly i.e. `@xxx.yyy.zzz` should match `yyy.zzz` in blacklist more info in [#46](https://github.com/martenson/disposable-email-domains/issues/46)
