I have set up rules to try to elimate the huge amount of spam mail i receive.  I set up rules like "If the subject line has the word sex - Delete from server"  etc or is the body of the message contains certain words then delete.  They still manage to get through - is this because the people sending them have worked this out and make the message body an image so that the words dont get picked up my live mail?

It is driving me nuts the amount of junk I have to delete every single day.  Ive tried blocking domains, moving them to junk before delete etc but nothing seems to work?

Any ideas?

thanks
