[draconas]

I have the same exact problem for my Yahoo account (There are threads on other boards going back to late last year). I ended up downloading the K-9 app from the Market and it seems to be working quite well, and a lot more configurable. Still figuring out how to get it to work with my work's Exchange, but that part isn't broken with the native app, only Yahoo. Would like to get both in one app if possible. Who knows, maybe it is all fixed in 2.2 (Froyo).
