For the past six months I’ve been successfully using Qurb to reduce my spam headache and it’s worked really well.
In effect, Qurb scans your e-mail folders and your address book for e-mail addresses. Then any e-mail with a new e-mail address is automatically moved to the “Qurb” folder where you can view the e-mails later and approve any legitimate e-mails. Those e-mails are allowed to remain in your inbox from that point on. It does a great job of keeping your inbox clear.
Since I last installed Qurb, at the beginning of June, it has quaratined 18,000 e-mails, which I am sure you’ll agree is quite a few!
Unfortunately as with all things spam, time is the greatest enemy. Over the past few weeks I’ve seen an explosion in the volume of spam being sent using legitimate e-mail addresses and therefore bypassing Qurb into my inbox….
As I’ve said before, the only solution to spam is hunting down the perpetrators.
