Evil Bastigiges! These products are the reason why setting up an open relay is not only dumb but dangerous and why blind gateways that auto forward error messages can also be just as dangerous. Finally! The idiots responsible for filling my firewall logs...
And thank you much for NOT cold-calling us ;) As for the notes of different ways to fool tools like spamassassin and mimedefang, any form of greek HTML and fumbled Base64 encoding that represents itself as the content of the message should be suspect, and I would figure it's only a matter of time before those techniques become flags in SpamAssassin on their own. The only way to reliably send spam all the time without the worry of various emails getting flagged by what ever open or closed products on the market is to send the message to specific recipients that ask for it, and to type it in plain english text with no attachments and no offer to sell you anything. But then again, I guess that's not very effective for use of commercial interests. hmm... You know, I'd be curious how the purveyers of this software would stand if challanged by the legal issues we raised a few weeks ago. Wonder if the folks at www.sueaspammer.com have heard of that site? Now that would be interesting... www.sueaspammerssupplier.com > From: "David F.
