What Is A Challenge Email?

If you are reading this it is most likely because you have received a "challenge" email from a Total Traffic Control server. This means that you have sent an email to someone who uses a TTC server for spam filtering. Your email has passed all checks and is not labeled as spam, however, your email address is unknown to the TTC server.

What To Do

It is simple, in your email program just click REPLY and then SEND. You do not need to type anything in the message. By replying to the challenge email, you will validate that the original email you sent was from a legitimate source and the TTC server will then allow it through. It will also create an "allowed" entry, so any future emails to this single recipient from this sender will not be challenged.
