I'm getting the following line at the end of all my received email headers:
x-open-relay: 184.108.40.206 is in a black list at list-dsbl-org.dnsbl.plus.net
Please can anyone tell me from where this is originating and what are the consequences?
The IP address refers to a server at BPWeb through whom I redirect mail from a domain that is hosted by them. They (BPWeb) say that this is something PlusNet are doing. DNSBL hasn't listed this server for about five months.
