Hi - for some reason, our domain is not receiving any email from just ONE particular domain. We do have a spam filter in place, but I checked that out and there is nothing being held up by the filter from this particular domain. Also, there is nothing locally on the pc (junk email filter) preventing emails from coming thru. We do use Exchange, and there is nothing being held up there as well. Also, they are receiving email from us just fine, we just dont receive replies from them or anything! just seems strange that its one particular domain. i'm not even sure where to begin! Help!
