chattr maildir

[Eric Persson <eric@persson.tm>]

Hi,

I just found some info about it beeing a good idea to chattr +A on 
Maildirfolders to prevent that disk i/o is wasted on writing the last 
accessed time, which is irrelevant in the case.

As I'm just trying it out, I figured, if I chattr -R +A  on a folder, 
will it apply to new files as well?
I did a quick test and it seems to be correct, but I cant find anything 
in the manpages that tells me this explicitly, does anyone know this for 
sure?

Or does anyone have any other pros/cons for this?

Thanks, Eric
