Sometime Today, Nagarjuna G. assembled some asciibets to say:
pine is not free software, since modified pine code or binaries cannot be distributed. please use mutt, which has more features than pine is a free software.
Although mutt still doesn't support dynamic signatures directly. You've got to use a vi macro and vi as your editor to achieve that (emacs works too). However, this solution won't let your sig figure out context from the reply role.
PS: no sigs in my mails from bombay since I can't get fortune to work on FC2.
