We seem to be getting a lot more spam getting through our filtering system. These appear to be using images with text on them rather than the usual spam which is pretty much 100% removed.
We use an external company to filter spam. I am considering using an additional filter within our network to try and remove the remaining spam.
I dont beleive it is possible to determive from an image what is spam and what isnt. They dop appear to have long names for the images though.
Is it possible to filter on images within emails and attachments based purely on the name and length of the image name or is this asking a bit much??
Any suggestions as to what would provide the best means of filtering image spam which I beleive is going to get very much worse over time.
Would the following Linux based application be better than a Windows based software solution??
