    Stock Pump

    I'm a newbie to this forum so hopefully this is in keeping with the charter of the group. I'm investigating a flurry of emails recently on Outlook. my email is attracting a what I call stock pump and dump. These emails pump a publicly traded penny stock, touting it as the next rising star. The email has evasion techniques, among them legitimate user and domain spoofing (joe[at]legitimatedomain.com), where of course the actual headers are anything but. It ends with several paragraphs of text I assume to penetrate email filter defenses. Most interestingly the email is bitmap or jpeg to bypass keyword search. The bitmaps are what I call "stitched" in multi-part, and rendered by outlook as a series of IMG CIDs like so: <IMG alt="" hspace=0 src="cid:001601c6b907$250e94a0$f0bdbf44[at]brxloc" align=baseline border=0><IMG alt="" hspace=0 src="cid:001701c6b907$250e94b7$f0bdbf44[at]brxloc" align=baseline border=0><IMG alt="" hspace=0 src="cid:001801c6b907$250e94ce$f0bdbf44[at]brxloc" align=baseline border=0> And so on. These images are stitched together by outlook and rendered as a seamless text message. I'd like to know if others are seeing the same thing, what is or can be done about it. On a related question, if I were to implement a filtering function on my emails, is there an open source spam filter or related links that can be shared with this community as a starting point? Thanks, /Steverino
