When we test in comcast explorer the fontsize is different than what we have coded. After live testing on someone's email we found that comcast is adding a class "msgbody" into our emails which is changing the font size to 10px.
It is also doing this with classes that have various font sizes.

We tried !importants and classes and adding it futher in and out of the td with no luck.

Has anyone had this issue or found a work-around for it?
