<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">mail deliverer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for postman that I've seen before include "Male to deliver mail" , "Mail deliverer" , "Chap with letters" , "TV's Pat, for instance" , "one delivers" .)
