Is there a difference between a mailbox and a mailbox?

Mailbox: if users send letters and need to affix stamps, they should put them in the postal mailbox at the designated place and be delivered to the customers designated by the envelope by the postman.

E-mail: ahem, generally speaking, it is a virtual e-mail transceiver station on the network, which is dedicated to individuals or companies, free or paid, and e-mail is in electronic form. Give the well-known Netease email registration link commonly used in China: (/mobilemail/home.do? From = 163 e-mail #). Generally speaking, e-mail has a fixed format: for example, qazzkk@ 163.com can be the exclusive account of your Netease e-mail.
