Someone, for the love of God, point me to a spam filter or script or WHATEVER that can filter out this specific image. If I have to look at it again, I'm going to scream. I think it needs to be some sort of OCR system because I suspect the image changes slightly with every mail. If you have any suggestions, let me know at tips @ gizmodo. I have my own IMAP server and use iMail.
UPDATE - Read on for some great tips.
But I've found that if you redirect all of your mail (as a catchall) and forward it to a GMail account, you can then use their POP service to retrieve it, which only retrieves the mail AFTER it's gone through the GMail spam filter, which is mostly great. If you have multiple email address going to different people, you can use an inexpensive POP retrieval package to rad the headers and send the mail to the right people.
I use this plugin called SpamBayes: http://spambayes.sourceforge.net/ They have plugins for all sorts of platforms.
I have never seen the image and I get more than my share of spam. I use an IMAP account and SpamSieve for Mac OS X. I get SpamSieve to weed out the spam and put it in a designated folder on the IMAP account and then periodically I train SpamAssassin (which is offered by my host, Pair.com). I only ever have to deal with the stuff when it's time to clean out that spam folder and train SpamAssassin. After it has been trained, any spam SpamAssassin finds just gets deleted before I even have a chance to interact with it. I tested the service out for a while before I implemented this part of the process and found that SpamAssassin was very accurate and could be trusted to work unsupervised.
Lunacy8m suggests Spamarrest.
I suggest never, ever using the Internet. And hiding.
