Hi

I’m trying to block email addresses from a particular domain - from which we seem to receive multiple spam user accounts per hour sigining up.

They come from .jil.kr where can be one of some 20 or so names I’ve seen so far.

I tried adding jil.kr but that doesn’t match, so then tried \*.jil.kr instead but that gives an error in the log that the regex is invalid as there’s no subject for the \* character, so I then tried (.\*).jil.kr and that doesn’t match either - I think because the . character in the brackets is being escaped.

Is it possible to add an entry for \*.jil.kr?
