It’s been around two weeks now since I implemented a technique suggested by Sean Sperte and I have to say it’s working brilliantly. I’ve gone from around a hundred (on most days) spam messages passing through my mailbox down to zero. Zero. Nada. Zip. Zilch.
Gmail has worked almost flawlessly at catching spam and forwarding legitimate messages with only 2 or 3 false-positives, none of which were urgent messages, so if you’re looking for a fairly simple solution to battling spam, I suggest you go read Sean’s blog entry.
