Server: 'pop.server.com', Protocol: SMTP,
Server Response: '550 Relaying is prohibited', Port: 25,
Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

If they sender is using outlook express or outlook (the properties are the same) go to TOOLs->Accounts->Mail->properties, on the servers tab down at the bottom make sure on the Outgoing Mail server section, the 'My outgoing smtp server requires authentication' is checked. The setting you are referring to is for outgoing clients to be able to send email. Remember POP3/IMAP4 is only a 'receiving' protocol, the sending protocol is SMTP, while by default you logon to receive mail, you originally did not have to authenticate to send email, you just pointed your mail client at an smtp server and it would send whereever you wanted it to go, but SPAMers did away with that option quick enough. Hope this helps.
