Mail problems

I just set up an email account and I have encountered some problems:

  • I can’t log into webmail because it doesn’t recognize my user/password either using the m9999 user or the joesomebody alias

  • In outlook express I can download mail but when I send mail I get the following error: (the is a valid address)

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ‘’. Subject ‘test 2’, Account: 'POP3 ', Server: ‘’, Protocol: SMTP, Server Response: ‘554 Recipient address rejected: Relay access denied’, Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
