You also need to make sure you do not have a signature release on file with the carrier in order for them not to leave it when a signature is required.
My PO has a form you can file if you do not want packages left on your doorstep. They will not leave anything that does not fit in the mailbox if they have that form on file.
All things considered, you usually have no control over how someone ships things to you...only over how you ship to others.
