DISCONNECT YOUR SYSTEM NOW!
The reason for this admonition (and its urgency) will become clear shortly.
The IP address in question is part of a (presumably DHCP-assigned) DSL pool in
Turkey:
<http://www.dnsstuff.com/tools/ptr.ch?ip=81.215.160.197>
<http://www.dnsstuff.com/tools/whois.ch?ip=81.215.161.29>
Note also that the hostname in question is now (well, as of two minutes ago
when I checked) resolving to a different address within that same pool:
<http://samspade.org/t/lookat?a=kelcos5.dynu.com>
<http://www.dnsstuff.com/tools/ptr.ch?ip=81.215.161.29>
And by the time you read this, it may well have shifted again.
This pattern strongly suggests -- no, scratch that; it is essentially certain
-- that your system has been compromised with a spammer's "zombie proxy"
trojan. It is S-O-P for them to "phone home" as soon as they take root and/or
find a live network connection, so as to alert their masters that they are
available for (ab)use and specifically where to find them/you. In all
probability, the host(s) it is attempting to "phone home" to are also zombies,
which the spammer(s) previously compromised. The dynamic DNS "service" is
being used to direct the droppers on where to report at any given moment.
Furthermore, the spammer in question is very probably one Kelly Joe Ellis, a
well-known low-life criminal scoundrel and all-around frothing loon:

<http://spews.org/html/S1532.html>
Since you yourself are (apparently) on a consumer DSL line:
> NNTP-Posting-Host: 80.242.254.221 (80.242.254.221)
<http://www.dnsstuff.com/tools/ptr.ch?ip=80.242.254.221>
<http://www.dnsstuff.com/tools/whois.ch?ip=80.242.254.221>
....that means that you are at this moment part of the spammer's "Zombie Army".
Hence: DISCONNECT YOUR SYSTEM NOW!
As long as your system remains connected to the 'net, it *will* be used to
spew spam, and worse, far and wide.
Do *NOT* reconnect it to any other system (either via your local LAN or via
the internet) until you are _absolutely_certain_ that the trojan(s) has/have
been completely eradicated. If that means wiping the disk down to the LLF and
starting over, so be it; but the main thing is that you MUST stop propagating
the damage still further.
