I am pleased to report on the performance of our two newest remailers, qwerty@netcom.com and nate@vis.colostate.edu. Both remailers had a very good response time.

Is it really a good idea to make anonymous remailers work so fast? Everyone who can analyze the traffic of anonymous remailers and can read the from/to header lines, the message size and the transfer dates immediately knows who sent mail to whom. The make the remailers more safe, I would suggest to modify the software: Every message must be sliced into pieces of standardized size ( e.g. 8K or 500 lines ). It should be possible to send the pieces over different channels. Every server should collect pieces and keep them a random time. Perhaps they could be collected until 10MByte of pieces are collected and then they can be sent out all. Every piece could contain a time limit which may not be exceeded by the servers. Higher limit means more confusion for a spy trying to follow this packet. The packets should be recyphered by every hop. They could have a random tail who's length is changed by a hop. A traffic spy could not find out which input and which output packets correspond. Hadmut
