What is so important about blocking by keywords in the subject?
Blocking keywords in the ‘Subject’ field is probably more powerful than address blocking, but not many people use it. E-mail address blocking has a drawback in that spammers use a variety of e-mail addresses, changing them often to get around address blocking. Subject blocking can be powerful in that you may block words like ‘viagra’, or commonly used features like double exclamation points, double question marks, etc. An enhancement from the previous subject blocker allows phrases to be entered, such as ‘make money fast’.
