Thank you, sometime I forget to RTFM. A 2 part question. abc.com 550 Spam from ABC.com
Will this match anything with abc.com, as an example if the message comes from m...@test.abc.com will it get rejected? Additionally in the doc I see REJECT and below that 5xx, do I need to have REJECT 550 We don't like you or does 500 We don't like you Work?
