This question was answered on February 15, 2003. Much of the information contained herein may have changed since posting.

A couple of years ago there were hundreds of relay servers on the internet where you could just go and send e-mails, and if you knew how, anonymously This of course was very nice, until spam companies started using them to send phony e-mails, you couldn't trace them back because the server would just send them, unconfirmed There are almost no relay servers anymore.

I assume that your e-mail server is located at, on the local network But you should know it's Internet address as well, for thet is where you recieve your e-mail Modern servers will not let any e-mail through without first checking if it's a real ip address or just a bogus one and is a special address and cannot be used on the internet Of course most spam servers can overcome that in their own maliciosly benign way, but you need to have a legit means.

Instead of sending your e-mail with account: try sending it with your servers internet IP address I do not know what e-mail software your servers is running (possibly MS eXchange?) so I cannot give you more advice than that.

P.S Please provide more information about your network and systems next time, I would be able to help out more.
