I've had endless trouble (as a listmaster) in the past with NTL email subscribers, although I haven't seen this sort of problem for a few months :( The usual meaning of 'open relay' is that someone logged in at a.com is trying to send an email to someone at c.com via a SMTP server at b.com (rather than a.com); this can be used for dubious purposes, as it makes the message appear to come from b.com rather than a.com, and is usually blocked by b.com with the type of message you see being returned. asda.gr seems to think that you, at ntlworld.com, are using asda.gr (rather than ntlworld.com) as the downstream SMTP server. From previous experience, this is because NTL is trying to be clever (for obscure reasons best known to itself) and rewrite email headers ... Unfortunately there's no obvious cure apart from resending until it works; I've had arguments in the past trying to get NTL to just handle email as it is. Alastair
