Steps to Reproduce
1. Configure Outbound Mail on ACS 6.2.2
2. Create a test user with a valid email address.
3. Request a password reset via REST API.

Expected Results
Images are not broken. Proper, current branding. Is the San Mateo office still open?

Observed Results
See attached image. Broken image links go to http://go.alfresco.com, for example the first image link is http://go.alfresco.com/a0100K050L0000KZjI2d00U
