What is a Mail Server?
A mail server is the computerized equivalent of your friendly neighborhood mailman. Every email that is sent passes through a series of mail servers along its way to its intended recipient.Without this series of mail servers, you would only be able to send emails to people whose email address domains matched your own - i.e., you could only send messages from one example.com account to another example.com account.
Mail Servers Types
Mail servers can be broken down into two main categories: outgoing mail servers and incoming mail servers. Outgoing mail servers are known as SMTP (Simple Mail Transfer Protocol) servers. Incoming mail servers come in two main varieties. POP3 (Post Office Protocol, version 3) servers are best known for storing sent and received messages; IMAP (Internet Message Access Protocol) servers always store copies of messages on servers.
