[Dovecot] Compressing existing maildirs

[Jan-Frode Myklebust]

I've just enabled zlib for our users, and am looking at how to compress
the existing files. The routine for doing this at
http://wiki2.dovecot.org/Plugins/Zlib seems a bit complicated. What do
you think about simply doing:

	find /var/vmail -type f -name "*,S=*" -mtime +1 -exec gzip -S Z -6 '{}' +


I.e. find all maildir-files:

	- with size in the name ("*,S=*")
	- modified before I enabled zlib plugin
	- compress them 
	- add the Z suffix
	- keep timestamps (gzip does that by default)
	

It's of course racy without the maildirlock, but are there any other
problems with this approach ?
