Two procmail/formail questions

I have a mailling list set up, but I have two problems with it.  One, I
can't get the From: line to be the address of the mailling list rather
than from me, and second, I'm curious if there's a way to parse out my
signature when it sends mail to all the recipients.  Any help would be
appreciated.  Thanks
