So, here is precision: AAT is a proprietary Mac OS X font technology  
from Apple (maybe doomed to die). It started as QuickDraw GX, on which  
XeTeX was originally written. AAT fonts were or still are for example  
Hoefler Text, Zapfino, Apple Chancery, Skia, some Arabic, Hebrew, and  
Chinese fonts,... AAT offers something like automatic, context  
sensitive, ligatures, correct use of medial and final forms.

Look, as a starting point, into Wikipedia (http://en.wikipedia.org/wiki/Apple_Advanced_Typography 
)!

No, it's mailer specific. (At least I do not of an OS, maybe except of  
GNU Emacs, that is used entirely for mailing purposes.) (http://en.wikipedia.org/wiki/Kill_file
