Since I got my Vibrant I have been testing several mail apps to work with my yahoo account. I tested the default mail app, Yahoo mail, K-9 mail, and Maildroid. After trying all of these I settled on the Maildroid since it was very easy to use, good interface, and actually worked as far as push mail. But one of the only issues I see with it is that if you reply to an email it does not indicate on the original email that it was replied to? Usually other mail apps will put in a arrow next to that email in your inbox to show a response has been set. I didn't see any options for it, but you would think that should be an essential thing to incorporate when coding a email program. Am I missing something here or the program actually does not have this feature?
