The short answer is, I don't recommend it unless you run your own server. Here is the reason. When you pick up your mail via fetchmail or what ever mechanism you are using, the chalenge/response software will examine the messages and send out confirmations. However, this does not happen until you pick up the mail, which is probably quite a while after the person sends it. Then, when the person replies, the chalenge/response system doesn't receive the confirmation until the next time you pick up your mail. I think you can see what will happen. Messages can end up taking a long time to be delivered to you. It may not be so bad with people who have an always on connection and poll their mail stores every few minutes, but I'd still say the ideal situation for a system like this is if you have your own domain and your own server running it. There are a few client-side chalenge/response solutions out there, but I don't recommend them for the same reason. -- Joseph C. Lininger jbahm@pcdesk.net Verification: 5eab38a77ac40416e075be8f50607ff7
