The easiest and safest way to hang something from vinyl siding is to use a siding hook.
Another site recommended finding studs and drilling through the siding to mount the mailbox with the option of caulk in the drill holes to prevent moisture from entering the wall.
Filled said holes with silicone caulk drilled the screws in to the desired depth applied more silicone.
The mailbox came with 4 screws maybe 1 long that can supposedly be used to mount it to a wall.
Press the insertion end of a hook up into the crack between one vinyl slat and the one above it.
Hang the mailbox insert screws into the top holes and hang on the wall only twisting the screws in halfway.
It slips into the groove between adjoining slats and once it clicks into place you can hang items as heavy as 12 pounds.
Marked the hole location on the part of the vinyl siding that rests closest to the the wall behind.
Once you decide on an appropriate mailbox to hang on your vinyl siding you can install it by first sliding the s hooks under and over the vinyl siding where you want to mount the unit.
Rest a level on top of the mailbox to double check it is flat.
You can drill through and mount the box over vinyl no problem.
