Email server

An email server is a system responsible for sending, receiving, and storing messages. The server is accessed by users through a client program, such as Microsoft Outlook or Apple Mail, using either the internet or a secure local network. The email server uses protocols, such as SMTP and IMAP, to communicate with other mail servers and deliver messages to recipients. Depending on the email server, there may also be built in filters for spam and virus detection.
