SpamSieve Comments

Awesome solution for spam victims

Positive Comment by Ragnir
about SpamSieve Oct 2016

There comes a time, when increased spam volumes start to get really, really annoying. The other day, I did a bit of research and decided to give SpamSieve a shot. After an easy installation and a bit of training on positive and negative examples SpamSieve already caught 52 spam messages the following day with one false negative and one false positive, which was easily corrected. I didn't even wait for the trial to end and bought a licence right away. Highly recommended.
