I have the same problem. Some emails are showing stuff like:

 

p { margin: 0; }

 

or

 

 v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);}

 

However, setting the above property to true does not seem to resolve the issue.

 

Any ideas? I really need to get this resolved.
