    Spam (OE6)

    What determines wether a message is designated as ***SPAM***?
    I received the usual crop of rubbish, but sometimes a genuine post, which has arrived as a normal message from a known Sender in the past is marked as ***SPAM***. Very puzzling <img src=/S/scratch.gif border=0 alt=scratch width=25 height=29>

    Probably some form of Bayesian logic is being used on a mail server (or maybe mail scanning software on your machine?) to determine a "spam likelihood" score, based on the words contained in the message. If the threshold is exceeded, then the message is marked.

    We have a program on our Exchange server which (among other tests) does this Bayesian analysis, and although it is pretty good, it is not perfect.

    It might also be what is in the Subject line of the email that is marking it as potential Spam.

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Most anti-spam software will identify itself in the message headers, toward the bottom. For example, SpamAssassin commonly uses that notation in the subject line, and includes the message's numeric score in the headers. To access the headers in Outlook Express, open the message and use File>Properties. (There might be a way to do it with the message closed, from the Inbox/junk folder, but I forget how...)

    Pretty straight forward Mike if this equation is anything to go by <img src=/S/grin.gif border=0 alt=grin width=15 height=15>
