Sorry, not possible. Postfix uses rename(2) to move message queue files between the various queue directories. The hold queue needs to be a sub-directory (in the same filesystem) as "incoming", "active", "deferred" and "corrupt" (if I'm not forgetting some). If the OP wants to periodically drain the hold queue of old messages into a long-term archive, the way to do that is to write and sync the copy file to its destination, then unlink the hold queue file. Best to use long queue ids when doing that sort of thing. -- Viktor.
