relaying problem

[Chester Chee]

When I try to send mail via smtp (using qmail), I got this error. MAIL FROM:
[EMAIL PROTECTED]@cal.arising.net instead of
[EMAIL PROTECTED] Any idea how to fix this is greatly appreciated. I
think this is configuration issues, but I am not sure where. I am using
Qmail 1.0.3, Vpopmail, MySQL, and TWIG (this is where I send my mail from).

Thanks in advance.
