Check that you can get to their domain, do an nslookup and get the MX record. Check that you can tracert to their mail server and telnet to port 25 of it. Basically try and work out where the problem is.

One Way Email Tris: Does this mean you have seen this sort of thing before? What puzzles me is we send out thousands of emails just fine. I just talked to our consultant again and he said there is some kind of conversion in our domain name going on, maybe the problem could be related to that. Bill It's the last bit - 'host unreachable' that is more important. Usually (from my experience) a DNS issue and if your ISP gets through could either be a DNS at your site or possibly a firewall issue at their site.
