I think the mists have cleared and I understand now where the problem lays...RR have obviously bothered to separate their Business and Residential IP ranges whereas good old BT have not.
and rr and AOL are sister companies (although that may make their relationship worse!!)
I will approach BT and see if they will relay outgoing mail from our server, without the need to change our domain address information.
AOL has justification. BTOpenWorld nets are huge sources of spam compared to legit mail (nil) from those nets, ime with many IMGate machines at many ISPs.
