Blocking emails

[nanaspain]

Hi to all you IT whizzkids.  I have heard that there is a quick and easy (please !!!) way of blocking certain domain names from which a lot of the junk mail is generated, rather than just blocking each individual message sender - which are invariably minor variations of the emails address you have already blocked.   Search as I might, I cannot find a way of doing it.
Simple, words of one syllable answers please.  Many thanks

Take a look at Mailwasher - I was using it in the 90's and it's still around - https://www.mailwasher.net/download-mailwasher-free - this is the free version, you can upgrade and pay for extra features if necessary.

Not sure if/how it works with hotmail ??
