Hi,

I'm trying to configure Outlook to work with my new mail
server. I've got the outgoing and incoming mail servers
configured correctly, and everything seems fine there. I
can recieve e-mails fine. But I cannot send them. Here
is the error I recieve when trying to send an e-mail:

The message could not be sent because the server rejected
the sender's e-mail address. The sender's e-mail address
was '(e-mail address removed)'. Subject 'test',
Account: 'pop.1and1.com', Server: 'smtp.1and1.com',
Protocol: SMTP, Server Response: '530 Authentication
required', Port: 25, Secure(SSL): No, Server Error: 530,
Error Number: 0x800CCC78

Does anyone know what the problem could be? Does it have
nothing to do with Outlook and something to do with my
mail server?

I'd appreciate any feedback, thanks in advance.
