See Don's comments from the parent bug:

Here are some minor suggestions on the layout of forum messages sent out from moodle. See the attached "forummailmessage.jpg" file which I refer to.
1. the breadcrumb links are a little too high in my opinion within the bar area. I suggest centering them within that bar.
2. the user photo should be part of the title/user/date horizontal bar. Now it appears to be part of the bottom background area. I suggest realigning it to match the title/user/date bar and use the same background.
