If you have .qmailadmain-hooks in either the /home/vpopmail/etc or /home/vpopmail/domains/domain_name/ directories and the ownerships are right then it should be working.
Unfortunately I don't know a good way to debug this.
Make sure you're running QmailAdmin 1.2.0 or later, as hooks were broken in previous versions.
