Subject Re: Capture IMAP events for use in our CRM
Date Mon, 30 Jan 2012 12:38:40 GMT
Hi,

If you are running in the james spring context, the easiest is to define 
your bean in the context and inject there the mailboxmanager (with 
@Resource annotation)

(See also my answers on previous mail).

Hopes this help,

Eric
