Hallo Everyone,

since some days a new dovecot version is available in Debian "wheezy-backports": (1:2.2.9-1~bpo70+1) wheezy-backports

As described in http://wiki2.dovecot.org/Plugins/Zlib and http://www.dovecot.org/doc/NEWS-2.2 "xz"-compression is available since Dovecot version 2.2.9.

Today I tried to convert my mailboxes with the new xz compression.

Therfore I changed my config as follows:

/etc/dovecot/conf.d/10-mail.conf: # Space separated list of plugins to load for all services. Plugins specific to IMAP, LDA, etc. are added to this list in their own .conf files. mail_plugins = zlib acl fts fts_solr

/etc/dovecot/conf.d/90-plugin.conf: # Enable these only if you want compression while saving: zlib_save_level = 9 # 1..9 zlib_save = xz # gz or bz2 or xy

Now I tried to convert my mailboxes - but somehow, something goes wrong:

root@SERVER:/# dovecot --version 2.2.9 root@SERVER:/# dsync mirror mdbox:/srv/converted_vmail/ doveadm(root): Error: zlib_save: Support not compiled in for handler: xz dsync(root): Error: zlib_save: Support not compiled in for handler: xz

Where is the failure? Did the packet maintainer forget to activate xz?

I can't find anything xz related in the debian package changelog: http://metadata.ftp-master.debian.org/changelogs//main/d/dovecot/dovecot_2.2...

Should I contact the Debian packet maintainer? http://packages.qa.debian.org/d/dovecot.html

Best regards

T.B.
