lotus notes secure mail, help configuring

Anyone conversant with configuring and using lotus notes and domino mail server for email encryption? I could use someone familiar with it to pick their brains on the topic. The purpose of this exercise is to find out the keys used in the lotus notes export versions "international crypto" implementation ("differential key escrow" or whatever it's called -- the 40 bits unescrowed, and 24 bits escrowed design). First step is to get it to encrypt something. I have a domino mail server running, and the notes mail client, but am having difficulty getting it to send encrypted mail. Please email me. Adam
