For work I get spam-l, and a general increase in spam would be reported there pretty sharpish. No such messages have been posted. The switch to PDF on stock spams means many content based filters are still catching up. This is another indication of the weakness of content filters to my mind. The greeting card spams are also a recent side effect of new Windows malware (search for "storm"). Again something that some content filters are struggling with, others considered all such greeting card stuff rubbish even before they started appearing with only IP addresses for the links. The only clearly growing problem I see is form submission bots. i.e. malware that submits forms. At work we have gone from this being a minor and occasional irritation to thousands of submissions a day every day in the last few weeks and months. Again clearly a retasking of spam bots. The sites promoted by these form submission bots are ALL (!) hosted on compromised web servers -- making me believe this is all the work of one spam group. There are only about 3 or 4 compromises that have become apparent, one in phpBB2, one in Lotus Notes, and one is some weird Windows webserver I'd never even heard of before. Amazing how much grief two groups of spammers, and some compromised computers can create. Simon PS: If you /dev/null email, you are filtering it wrong. We reject well over 99% of all incoming SMTP connections, without going anywhere near /dev/null.
