[lug] Remove files not owned by anyone.

[Paul Nowosielski]

Dear All,

I have a weird problem. I'm migrating users of postfix to  new server.
After taring up the virtual directory and migrating I noticed this with one of 
the accounts:
?????????? ? ?          ?             ?                ? courierimapuiddb
?????????? ? ?          ?             ?                ? maildirfolder

These two files are owened by ? and can't be removed !

Ex:

# rm courierimapuiddb
rm: cannot remove `courierimapuiddb': Permission denied

This is as root. 

So I shut down postfix and imap thinking the files could be in use with no 
luck. Any suggestions to solve this?

Thank you,
