I'm assuming that the bulk of my email spam is from friend sending me ecard.
I get on the average of 3 to 10 mail spams perday but 9/10 is caught by my MailWasher. It is too bad that it can't be set to run as a service, but setting an agressive black list & friend greatly reduce the spam & the email have to be addess to me directly in the to: cc: box.
black-list any thing in the to or cc field that contain: *0* to *9*, *yahoo*, *hotmail*, *service*, *school*, *money*, *certified*, *exam* & *business*.
