When run manually, the process works and unless the -v is added, there's
no output. This one is part of the iPlanet message server that among
other things, cleans out messages that have been flagged as deleted.

All I'm expecting back at the moment is a 0 or 1.

I'm wondering if there might be something there I'm missing as well,
perhaps adding open3 would give some insight.
