Hi, wonder if anyone can help me sort this one out...?;

I got the following message when trying to send an email from outlook
express;

The message could not be sent because one of the recipients was rejected by
the server. The rejected e-mail address was (removed for privacy, it doesn't
matter what email address i try to send to, same message comes up). Subject
'Read: Item number: 150305184567_proof copy enclosed', Account:
'imap.1and1.co.uk', Server: 'auth.smtp.1and1.co.uk', Protocol: SMTP, Server
Response: '550 must be authenticated', Port: 25, Secure(SSL): No, Server

thanks for any help


The part about, "550 must be authenticated" is very explicit. In MSOE, Tools
| Accounts | Mail, click on the "Properties" button for the affected
account. On the "Servers" tab there is a section labeled, "Outgoing Mail
Server", with a box labeled, "My server requires authentication". Put a
check in that box.
