can't be too hard to fix.

i assume it issues a STAT.  this is how you do it in limbo:

-     (e, s) = request(CMD_STAT, nil);
-	case e {
-	ERR =>
-		return(s, big 0);
-	OK =>
-		if (debug)
-			sys->print("%s\n", s);
-	}
-
-	messages := big 0;
-	size := big 0;
-	(n, l) := sys->tokenize(s, " ");
-	case n {
-	1 =>
-		sys->print("%d message%s for '%s@%s', maildrop size unknown.\n", int messages, plural(messages), user, host);
-		messages = big hd l;
-
-	2 =>
-		messages = big hd l;
-		size = big hd tl l;
-
-	* =>
-		return (sys->sprint("unknown number of messages for '%s@%s'.\n", user, host), big 0);
-	}

then loop over messages.
