Try munging qmail-pop3d so that it always reports that one more piece
of mail is available than really exists.  When the client software
tries to download it, send them nothing -- just hang.  Wait for a
single character to be written to a named pipe.  When that character
arrives, open the first piece of mail you see, and send it to them.
Write that character to the pipe using a .qmail file like this:
    ./Maildir/
    |echo >Maildir/.waiton

Then tell them to poll the pop3 server every zero minutes.
