Once you've performed a full capture on port 25, Wireshark does a nice job of providing an option to extract the relevant conversation by right-clicking on just one packet in that conversation and choosing something called "Follow the TCP stream", I believe. Ok. I've never captured in tcpdump and then imported into Wireshark before, but I'll do some tests, scp the file to my Windows workstation, then follow the stream. Once I ensure I get a clean stream, I'll post the results.
As I research the documentation on the how-to specifics on capturing with tcpdump in a format that is Wireshark compatible, is there anyone here that could perform a simple test against their own domain email system, that can confirm or deny what I have been witnessing?
Wireshark reads pcap files. Spit them out with this option on the tcpdump commandline. -w file -- Nathan Ward
