I'm using WinPcap to capture packets, and I notice that I'm able to see
the text of many things like IMs (instant messages) and outgoing emails.
However, when I load a web page (for example, reading my yahoo mail) I
can "see" the headers of the email and the subject line, but the body is
all garbage--to me--is this encoded? How can I decode? I'd like to be
able to save certain emails to file, but first I'd like to filter them
as I read them from online.

Thanks
