Each message contains magical unique information for the specific user.
The way it's done right now (in sendmail) I wrote a perl script that writes
the queue files. This uses file locking and since sendmail is caring about
locked files it won't try to send them while they're still being written.
You don't suggest using qmail-inject to insert the files into the queue's?
It may be a little slower since it has to fork a new process for each mail
but I figured that would solve any flock'ing issues.
