[Dovecot] maildirfolder is created world-writeable

[Robert S]

If I create a new folder using a mail client (eg. kmail/OE), the
maildirfolder file is created world-writable.  I assume that this is a
security risk and should be -rw-------.

eg. - create folder "Foo" in mail client

 ~ $ ls -la .maildir/.Foo/
total 20
drwx------  5 robert users 4096 2009-01-21 19:56 .
drwx------ 43 robert users 4096 2009-01-21 19:56 ..
drwx------  2 robert users 4096 2009-01-21 19:56 cur
-rw-rw-rw-  1 robert users    0 2009-01-21 19:56 maildirfolder
drwx------  2 robert users 4096 2009-01-21 19:56 new
drwx------  2 robert users 4096 2009-01-21 19:56 tmp

I can't find this is the bugs area.
