I installed openerp in my local server (192.168.0.228). My Email Server is 192.168.0.227. I already test my outgoing email. And it's correct. I already edit my server aliases to 192.168.0.227. setting->general seting when i look in admin user the aliases is admin@192.168.0.228

When i send an email it's got an error like this.
