When using mass mail marketing with images on a Odoo 8.0 server with multiple databases, the images are broken in the e-mails. The problem is that mass mailing uses http://<server>/website/image/ir.attachment/..... to load the images from the Odoo webserver. This is no problem with a single database, but how to deal with multiple databases?
Or is there a way to encode the images as base64 in the e-mail?
