Did you try changing the font? I also use this awersome mail appSorry for delay, i solved. It was an error during flashing. I deleted the *.md5 file and flashed the zip rom without problem.
Now the only problem that i have is that in the apps like aqua mail (or other apps where is a text), i don't see written in bold.
The photo attached is an example how it was before when it worked well with previous roms.
