OK, I've decided to try to make my own patch to include these functionality. Please be awared that this is my first pacth ever, so comments and corrections are more than welcome. Anyway, the included patch intended to add the functionality of skip graylisting mechanism for authenticated users, and it seems it works (at least for me on two servers).
Looking forward to hear comments.
For very quick look, it looks ok. (no string handling, so it might not create secyrity problems ) ;)
