Any and all feed back regarding this idea is welcome.
if you control the end-user sending machine & it runs some sort of Unix, this is trivial; the required command is just: at 04:00 mail whoever@example.net < message_file Writing a script to do this using a random time would not be hard. Of course this does not encrypt the file, though it could send a file that was already encrypted. Nor does it provide any sort of protection against someone who can snoop on the sending machine (nothing I know of does!), so it does not work in your Internet cafe example. Better to modify the mail server to introduce a random delay. This also does not look hard. Avoiding time stamps in the Received: lines in the headers would also be necessary, but that looks straightforward as well. To block tracking, you also want to avoid putting the client machine's IP address in the headers. Easily done, but it makes it harder to deal with spammers.
