Question ID: 524049
I constantly receive 2 or 3 emails daily that escape all my security controls and are so strange. I know they are some sort of trouble so I never open one. The sender is never the same address but they all have one thing in common--that being highly mispelled words in both name and subject. Most of the time it is something you can make out what they are "trying " to spell. It is no big deal, but I would give $5.00 to know what the heck this is all about. Anyone know?

Hi instanswer, Most likely, you are getting unsolicited commercial electronic mail, commonly known as "spam." The senders want you to see their messages, and you don't want to see them, so you use filtering software to get rid of the messages before you see them, and the senders try to evade the filtering so you see the messages anyway. The misspelled words are a technique for evading filtering, which seems to be working at least some of the time in your case, because you are seeing the messages. For example, your filtering software may be vigilantly searching for the word "Viagra" as a spam indicator. If the sender instead spells it as "V1agra," the filtering software may not recognize it, but the intended meaning is clear to a human reader. A couple of web pages that mention this technique: http://www.wired.com/news/infostructure/0,1377,60941,00.html http://www.mtamicro.com/rb/rb031705.html I hope this is a satisfactory answer to your question. If you need any more information, please ask for a clarification. --efn

I've written an article that deals with this type of spam attack, including recommendations of software to get rid of it: http://www.andybrain.com/archive/stop_spam.htm I've had really good results with both products mentioned. Andy
