I know you recommend not to enable anti-virus because of adverse affect on flash drive life but this morning I had 1000+ messages waiting on just one account. Valid emails were less than 10. My current spam filter (Spamihilator) had a 99% efficiency. After 2 weeks of training PTB, it let through more than 12%. There were still about 125 messages (115 spam) to go through. I for one would rather replace my drive every 3-4 months than wade through all this spam. Great site and Great tools. Many thanks for your work. Donation to follow.
