Does you host have any documentation or examples on sending email through their mail server? Does their mail server require authentication (a username and password) ?
I couldn't find any documentation on Sun's site about sending email via Chili!Mail through a mail server which requires authentication. I'm not sure that CHili!Mail supports it.
The only two components in inc_mail.asp that contain code for sending email via authentication is CDOSYS & ASPEmail. You cannot use either of those on a RAQ.
Does your host have any examples? Or could they set the mail server to allow your i.p. to send mail without authentication?
