I'm now facing the same issue with 2.2.13. zlib is working for new mails but as opposed to some information I found dsync (backup) does not convert old mails to compressed. For example this post suggests that it should happen: http://thr3ads.net/dovecot/2013/07/2663810-dsync-backup-mails-compressed and also some Dovecot book also states to convert the mailbox just use dsync backup after zlib is enabled. Still I'm not able to make it work.

You have to set the compression type with the zlib_save option.

i.e.: "-o plugin/zlib_save=gz"
