How to configure plugins?

[chihoko]

Before upgrading to the latest release we used our own plugin file

dovecot::file { 'conf.d/90-plugin.conf':
  source => 'puppet:///modules/site/dovecot/90-plugin.conf',
}

Now this file is declared in init.pp and the 90-plugin.conf.erb template doesn't allow custom configuration of plugins. How are we supposed to configure plugins now? E.g. we use the 'autosubscribe' and 'autocreate' plugins.

Cheers!
