Spam is a massive 98% of all email traffic, most from infected computers around the world. The best way to stop spam is to actually be integrated into the email server, so spam can be identified during the SMTP handshake phase. Even more importantly blocking instead of email filtering offers you more protection against new attacks, whether they be text Spam or in images, videos, attachments, or even encrypted messages.
Spam Experts does all of this, whilst being easy to use and easy to understand. Like other software, Spam Experts has constant updates, and protects all your email addresses.
