I set up a secondary mx wondering if this could be used to set up stricter spam
filtering. Almost immediatly after adding the mx and reloading dns I started
getting mail to it. Almost all of it is being rejected. I inspected one that
passed and wonder about that one. Looks like the sender address failed but got
delivered any how?
