Cursor positioning

[Springfield]

Hi, When I edit certain files (emas and news group postings) I use
mail fill mode and have a function that is executed when the files are
loaded. Within this function is the command:

(goto-char (point-max))

to put the cursor at the bottom of the mail. The trouble is I would
now like it above my signiture but still below any quoted text. How
could I achive this?

Thanks alot and best regards
Springfield
