[Dovecot] Unknown setting: plugin after fresh install

Hi guys,

I've installed dovecot 2.1.7 on a Debian Wheezy, tweaked some parameters little bit, but I can't restart it (dovecot -n also fails) and get this error:

doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/90-acl.conf line 11: Unknown setting: plugin doveconf: Error: managesieve-login: dump-capability process returned 89

Wether I uncomment this plugin line, I get the error on another file (example 90-quote.conf). Seems a little bit weird. What have I done false?

Thanks Patrik
