It is posible that the destination smtp server uses RDNS (reverse dns). This means that, before actualy accepting a e-mail by the smtp server it wil first check if the reverse dns of the e-mail domain corresponds with the IP address from whom you are sending that e-mail. If this reverse dns fails your e-mail will be rejected. This can be resolved by asking your dns administrator (mostly your domain registrar) to create a pointer to your fixed ip address. But it can be something else to. You could ask the destinator if they use reverse dns for SMTP. Or maybe some kind of black and white listing could cause this to.

I've spent the past half hour on the web trying to find out precisely what this means, and have come up with absolutely nothing. Does it just mean that it failed and no-one knows why? How do I fix it? Jon The information in this e-mail is confidential and may also be legally privileged.
