It's not exactly small, but fairly sure Exim will do what you want. As one of the commoner mail servers, you'll find loads of documentation on-line. Many not be simple to set up though.
I haven't played with Exim for ages (or Qmail, for that matter), but if pushed in the direction of a real mail server I'd probably go with Postfix just because I know it (for some vague definition of "know"). It just feels like overkill.
