How do you stop receiving old tenant's mail?

Answer:
My method was to write, "Return to sender: not at this address" on the mail, and put it back in the mailbox for the mail carrier to pick up and take.

Added: Or go to the local Post Office from which your mail carrier operates and speak to the Counter Clerk or Postmaster.
