Postman

A mail carrier, mailman, postal carrier, postman, postwoman (US), postman/postwoman (UK), letter carrier (in American English) or postie (in Australia, New Zealand) UK is an employee of the post office or postal service, who delivers mail and parcel post to residences and businesses. The term “mail carrier” came to be used as a gender-neutral substitute for “mailman” soon after women began performing the job. In the Royal Mail, the official name changed from "letter carrier" to "postman" in 1883, and "postwoman" has also been used for many years. [Mail carrier. Wikipedia]
