I may be wrong, but from your email headers, it looks like you are mailing from a computer connected via dsl. Are you running an smtp server for yourself (i.e., internal mail, getting mail from external source and sending via an exim smarthost) or are you actually supposed to be relaying mail for other machines? I am connected with DSL and retrieve mail from three different sources. I run fetchmail to get it and exim to send it out. Exim is configured to send mail for the localhost only and it passes it all out to my smarthost. Also, ipchains blocks all smtp traffic, except from the smarthost. And finally, I have telenetd running from xinetd.conf, but it is bound to my internal NIC, so there isn't an open telnet port on the internet. Maybe a configuration like this would work for you?
