"I'm the heaviest user of e-mail in my office, sending an average of 75 e-mails per day and receiving even more. Total Email Defense has made my working life so much more productive. I used to spend about an hour a day in lost productivity just trying to handle the glut of spam and unsolicited e-mails I would receive. Total Email Defense eliminated a majority of the spam I was receiving in the first two weeks.
"Now I get a few quarantine e-mails per day from TED. That's actually great to see because I know it's working!"

The following is an excerpt from the Technical White Paper on Total Email Defense assembled by Ron Edison, Founder and CTO of IDT, and his development team.
Blocking Spam & Mal-ware at the Mail Gateway
Technical Specs of pre-transmission channel establishment email rejection
The first element here is that TED rejects messages before the mail transmission channel is opened and before the system has expended resources to process, analyze, virus check, attachment check and continue with many other resource intensive operations. This first key step vastly reduces mail volume, bandwidth utilization and generally allows mail systems to do what they were designed to do in the first place -- deliver email. Many other commercial products, appliances, hosted anti-spam services, et al, miss this critical step, so fruitful in rebuffing spam en masse.
As a backdrop to this, spammers have been exploiting these characteristics of the SMTP protocol for years, faking the return path and delivering messages to users that are ultimately nearly impossible to trace. Thus, TED turns this against them, rejecting huge quantities of mail before the mail gateway expends any resources examining message content.
