Recently I gzipped mails older than 30 days in our users' maildirs. I used find and gzip. Gzip added 'Z' at the end of the filename and everything seemed to work fine, users did not notice any difference in performance (yet :-), and I saved about 30% of our mail storage space.
There seems to be a problem when moving gzipped messages from one folder to another though. Dovecot drops the Z flag, moved messages are not processed by the zlib plugin and email clients end up showing garbage.
Is there something wrong with my config, or did I encounter a bug?

maildir_copy_with_hardlinks: yes
Hardlink copying is broken with zlib plugin. v1.1 works differently and it works there (although non-hardlink copying was broken there, fixed only in hg).
