My wife banged the mailman?

Your post title is VERY badly worded LMAO.

It happened on your property, so could be either. Hopefully both your cars and home are covered by the same company -- that way you don't have two companies fighting about who pays out first. My best guess, your car insurance will probably pay out first. If the claim exceeds your auto policy, then the homeowners would kick in at that point.

You would file a claim with your auto insurance provider.

-licensed agent

I'd say auto insurance since its your car. No part of your home has been damaged.

Ask your agent. You wife banged the mailman, well I guess it means different things to different people.

Sounds like you have bigger issues. Careful of your phrasing. Regardless, have your insurance agent give you your options. That's why you give them your hard earned cash, let them do their job.

You should settle this thing with the mail man on your own. Man to man.

what's it got to do with the house ??

( tip ).............. in the future,check the wording of your questions
