It's likely just unburned fuel. Perfectly normal when an engine is running at idle. Especially so when first started and not yet at normal operating temp.
No. Unburnt fuel is called gasoline, and doesn't come out the tailpipe. That would be an instant emissions failure and a huge environmental problem.
It's condensation, which happens when the pipes cool down and consolidate accrued humidity from the air. That's why there's typically a little weep hole in the muffler. When you restart the car, exhaust gases blow the accrued water out of the tailpipe.
But correct - Not a problem.
