So, I registered a new domain name and set up two e-mail accounts to use with Outlook Express. I've set everything up and both accounts will send e-mail, but will not receive. When I check the box for password authentication it gives me this error:

Unable to logon to the server using Secure Password Authentication. Account: 'eBay', Server: 'mail.twok3ebooks.com', Protocol: POP3, Server Response: '-ERR Command not implemented', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC18
Basically, extremely annoying, because I have everything correct and have no idea what could be wrong. I'm awaiting confirmation e-mails and, of course, would like to be able to use the account to receive e-mails and not just send them.

Any help would be great!
