Blue Security (blue frog) says they will spot spam messages. But 2 months later after I installed it and gave them my email address, they gave me a message saying that they will spam me!! Unbelievable! Over a million users got spammed thanks to blue security!!!

Pros
It WAS a gread idea.
Cons
The company ceased anti-spam operations. No wonder I couldn't get it to work! Go to bluesecurity dot com to read what happened.

Pros
Good idea gone bad!
Cons
My email has been hijacked/spoofed, whatever you choose to call it. Is now being used to spam addresses worldwide. I resent this, no effort to correct has been made nor has Mozilla (proud sponsor of Blue Frog) bothered to put a caveat on their site. Those that still think it's great, good for you. Find a legitimate site with competent personnel or simply ignore the spammers. We will probably eventually be listed as a spammer, that's unfortunate. I cannot begin to adequately say how much I resent Blue Security and Mozilla/Firefox.
