Hmm, I would be slightly concerned. As you might have guessed, random stuff isn't supposed to ooze out of the exhaust system. The best thing I can recommend to you right now is to check your coolant level and record it. Then keep checking it over a few weeks and see if you're slowly losing coolant. If you are, then that's not good. If you are not losing coolant, then that might be just some type of condensation in the exhaust system and/or engine.
