I enabled zlib compression, so new mails are saved compressed. Now I want to convert the old mails to gzip with the find and gzip command, but now I don't know which files are already gzip compressed by dovecot. Shouldn't zlib_save itself add Z to the Maildir flags? As suggested in the compress guide on http://wiki2.dovecot.org/Plugins/Zlib ? -- Tom

I suggest to do not use script that rename email files because they can invalid the uidlist. -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

I worked around it with `file`.>> Shouldn't zlib_save itself add Z to the Maildir flags?

If it does, then the wiki should be changed. // Tom
