[qmailadmin] mail not deleted

[Alex Dean]

Via the qmailadmin control panel, I edited an account and selected  
'Routing' = 'All Incoming Deleted'.  But new/incoming mail isn't  
being removed, it's just sitting in the inbox.

I have vpopmail installed in /var/vpopmail, and in /var/vpopmail/ 
domains/domain.com/user/ there is a .qmail file with the contents '#  
delete'.  I think that's correct, so why is the mail not being removed?

thanks,
alex
