What are the message properties?   Particular sizes?  Maildrop behaviour
differs depending on messages size; particularly, it will cache small

Be sure to capture its stderr somewhere you can find it. Perhaps
redirect it to a separate log file.

This, however, goes beyond what Jonathan wrote: user ids, environment,

How exactly does Postfix integrate with maildrop?
