I've seen lots of posts about embedding an image (eg. the company logo) as base64 within the email template.
But this technique **does not work** with Outlook (actually it works if you tweaks some registry keys in the Windows of the computer running Outlook... but it's not a feasible solution, isn't it?)
Another option is publishing the logo on some http accessible URI and linking it from the template, and hoping that cross-domain policies won't block it... (Microsoft' fears here again)
Is there a globally working option, which works both with Outlook (.com and host application) and with other commonly used email clients?
Or is there a module to attach the image as a multipart?
