Mailing Servers

Mailing servers are software which is capable of transferring electronic mail messages from computer to another with the help of a client-server application. The building of the software utilizes some standard protocols, to enable it to transfer both messages and data files.

Mailing servers function by allowing the mail recipients to access messages sent. However, the functioning utilizes different protocols, with POP3 and IMAP being the most common.

Simple mail transfer protocol is used mainly because:
