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
As long as it doesn't find any already compressed mails..
- compress them
- add the Z suffix
Make sure there's also :2, suffix already. If someone hasn't logged in for a while there are such files in new/ directory.
It's of course racy without the maildirlock, but are there any other problems with this approach ?
Other than being racy, I guess it should work.
