recipients was rejected by the server. The rejected e-mail
address was '(e-mail address removed)'.

Response: '554 <[email protected]>: Relay access
denied', Port: 25, Secure(SSL): No, Server Error: 554,
Error Number: 0x800CCC79

This is the error i receive. Anybody can help me solve the
error? I can't seems to find the solution for it.

Thanks a lot.

This newsgroup is for support of Outlook 97, 98, 2000, 2002 & 2003 from the
Office family for Windows PCs. For Outlook Express (OE) support try posting
in one of these newsgroups:

If those groups aren't carried on the news server that's carrying this group
