[Dovecot] plugin expire

[Felix Rubio Dalmau]

Hi everybody,

        I'm trying to configure the expire plugin, unsuccessfully. This is my 
configuration, the part related to this plugin. Could somebody give a look to 
it? I can not figure out why is not working :-S. 

        Thank you, and regards!

        Felix
