Andrew, When I attempt to send mail through UKonline' SMTp server to say dolphinusers@xxxxxxxxxxxxxxx with my yahoo.co.uk address as sender, it appears to be accepted by the Ukonline server but then I get a Mail Delivery Failure notice "550 relay not permitted" Messages sent in exactly the same way to any address other than yahoogroups go through normally. Any ideas? I am baffled at present.
