Yes, and in order for my mail server to accept the mail from [EMAIL PROTECTED] going out to [EMAIL PROTECTED], the visitor must either be authenticating via SMTPAUTH (not gonna happen, visitor accounts are a pain) or my mail server must be configured to allow relaying of non-local mail without authentication. Also, if the visitor's MUA is configured to use authentication against their ISP's real SMTP server, the authentication would fail against my SMTP server. > I'm assuming that your occasional visitors are on your internal net off > course. they are, I suppose I could configure the mail server to allow relaying for all internal network addresses but that doesn't solve the AUTH problem and it puts an unneccessary load on my servers. It also makes my mail server the target of RBLs and anti-spam measures should a virus or SPAM zombie slip through. I downloaded ClamSMTP and installed it no problem, does exactly what I was hoping for. Jay -- Jay Lee Network / Systems Administrator Information Technology Dept.
