When testing via manual smtp mailing, I can verify that the script runs, but it doesn't do anything with the result and qmail continues to accept the connection despite no user existing.

Well, from looking at the code, it looks like the script automatically determines whether it's running via qmail-spp by looking to see how the recipient is passed.  I'm not sure how you're calling the script, though it should be in the rcpt section of your plugins file.

Once a determination about whether or not the recipient is valid, it either drops through, or prints out the text in MSG_ERROR ...  The default script prints out a simple error rejecting the smtp command.  If you want it to reject instead, just change the leading E to an R.
