What if almost every future spam would > consist of some image and GPG signature? Each of those elements have some constant characteristic. In fact, having spam signed with GPG would make it easier to filter out - you could have your LDA check the signature, verify it and cast away should it fail verification. > Filtering every such mail isn't a solution for me. How come? You have to filter every mail in order to see whether it's spam or not anyway... There is a tool that does a very good job for keeping spam away from your box if you're willing to put some effort in configuring it (I'm not using it personally, but my boss is - with a great success) - http://www.tmda.net/ > In fact mails with GPG signatures had some possitive score in my > procmail. Now I have to remove it :/ I don't think it is a good idea anyway, it's like leaving a passage for possible spam. regards, marek
