Integration with the smtp server of OpenERP

Actually, we must specify smtp credentials in the parameter of openerp server in order to sent email with some feature of OpenERP (Like Send Prospect & Historize in CRM.Case , or the action mass mailing in Partner).
This feature should not use anymore the openerp server but poweremail when it is installed. So, we will able to specify the account smtp to use to sent the mail.
Moreover, the mail that the customer resend in response for a mail generate by CRM case should be historize without use of fetchmail. I'm sure it's possible to do that with Poweremail.
If we can do it with Poweremail, i'm sure all will be ok for saying it's the best solution of emailing for OpenERP. All work you have already done are amazing.
Thanks.
