Hi Guys,
I'm trying to block an individual email address from reaching my domain, i would like it to fail. I've set up a rule under both user and account level filtering and it doesnt seem to work. I've tested it on myself and 1 out of 5 times it blocks the email, the rest of the time i receive the email. Any ideas? any other way you can think of to block someone from emailing my domain?
Thanks!
