Just discovered this website, so hello. I'm temporarily on "steam-driven" dial-up for three months. Everything fine until Friday, 10th Jul. Now I can't send emails, getting: "The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'xxxxxx.xxxx@xxxxxx'. Subject '', Account: 'pop.virgin.net', Server: 'smtp.virgin.net', Protocol: SMTP, Server Response: '550 Administrative prohibition - relaying not allowed', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79." I use Outlook Express, I have been having problems with Internet Explorer so I am using Firefox for the internet, and I connect through UK Telecom. I hope all that makes sense, as I haven't really grasped the whole process of connections and accounts, etc. Anyone there who can help me?
