Letter: Could 'Permission' Method Filter Out Spam?
I recently e-mailed a business associate for the first time after speaking with her by phone and getting her permission to send some attachments to her e-mail address. Her server had a filtering system that allowed her to reply to me first, notifying me that she was using a filter and asking me to reply from my e-mail address so that my e-mail address could be added to her database of "allowed" correspondents.
This "permission" method seemed to be a good way to compile a list of bona fide correspondents and filter out all the other unwanted spam.
Is this a feasible solution for the rest of us who are having to rely on other types of filters that work only from finite lists of unacceptable words, topics, etc?
