Description of problem:
Default message font size  (i.e. if preferences is set to be the same as other applications) is horribly small. To get the font to display the same as say 10pt on MS Outlook, you need to set to 14pt in Evolution.
I think this is may be a Mozilla rendering bug.

Version-Release number of selected component (if applicable):
evolution-2.1.5-1

How reproducible:
Always

Steps to Reproduce:
1. Start Evolution with default settings
2. Receive HTML message with no formatting

  

Actual Results:  Fonts are too small - (same as 6pt on MS Outlook)

Expected Results:  Text is readable

Additional info:

Can work around by changing message font size
