Default leak around base of furnace exhaust pipe

If it's coming out of the exhaust, it's possible that it's flue gas
condensate. If that's the case, it's either somewhat corrosive (gas
heat) or very corrosive (oil heat). Is your furnace one of those
brand new high efficiency units (with commensurately very low exhaust
temperatures)? Chimney is on an outside wall of the house?
