I am trying to discover which machine on my local network is causing our static ip to be listed on a DSN Blacklist.

I've got Kerio setup to relay messages to our ISP's smtp server, yet, I also see other smtp connections when I run a netstat command. Does this mean my server is part of a spam botnet?

Thanks in advance.

PS. I've included a sample of my netstat output.

In my example the first 2 are to my isp smtp servers. The second two are to other smtp servers:
C:\Documents and Settings\Administrator>netstat

Active Connections

Proto Local Address Foreign Address State
TCP mail:smtp TIME_WAIT
TCP mail:smtp TIME_WAIT
