I took it to the mechanic and he almost immediately noticed the water pump was leaking. He replaced the water pump but that wasn't the problem...
There's no problem if I drive from place to place but if I allow my Jeep to idle, it never fails to over heat. This is a problem because I use it to deliver newspapers in the morning with lots of stop and go and idle time between houses (having to run up to houses and back to the car). Turning off the car and restarting it between stops isn't practical.
Anybody else have the same problem? HELP!

Gabsy has some good suggestions. However, I would check/replace the thermostat. It may be partially sticking closed. Or check for residue/junk in the radiator which partially blocks coolant flow.
After the car is warm with the radiator cap off, rev or have a partner do it as you look into the radiator. You should readily see the coolant moving. You may need your radiator flushed, including back flushed. The mechanic who did the water pump should have done this.
You may also have a air bubble in your system. When you change/replace fluids you should leave the car running as you slowly pour it in. As it gets hot you will see the coolant rise with bubbles coming to the top. You should do/allow this to happen till you see no more bubbles. Replace the cap and then slowly fill the reservoir.
As for your thoughts of turning off and restarting your car, "isn't practical", is wrong.
Idling your vehicle for more than 30 sec at a time uses/waste more gas, thus reducing your MPG. If your car is in tune it only takes a second to restart it. You might enlist a friend/helper to run up to the houses.
I have been shutting off my engine at stop lights (some have a 3-5min wait) for years. It makes a difference.

once you put in the recent relay, did you sand the rust off the mounting pad? Did you coat the back of the relay with dielectric grease? Did you sparkling the grounding screw? If no longer, the relay won't artwork or will fry very today. It cools and gets floor via touching steel.

there is a relay switch that controls the electric fan. When it goes bad the electric fan runs at inappropriate times. Switch is $24 and is located in the fender area. A little difficult to get to.
