I think you meant "border mail"!

Border mail refers to the postal service that operates along international borders, particularly in areas where there are no formal postal services or where the postal services of two countries meet. Border mail is often used to deliver mail and packages between countries, especially in remote or hard-to-reach areas.

In some cases, border mail may be handled by a specific postal service or agency that is responsible for delivering mail and packages across international borders. For example, the United States Postal Service (USPS) has a Border Mail program that delivers mail and packages to and from Canada and Mexico.
