That is essentially correct.  However if the mailing results from
forwarding via a '.forward', then the permissions of the owner of the
'.forward' are used.  Likewise, if the alias is a ':include:/path/to/file'
and the included file has a program alias, the permissions of the owner
of the included file are used.  However daemon still replaces root.
This is for extra safety.

If you want more control over permission during delivery, I recommend
you install a delivery agent such as 'deliver' (from
comp.sources.reviewed).  This will also do file locking while delivering
to a file - cat won't, so the file could be clobbered it two messages
arrive at about the same time.
