What is a Mail Server?
By click of a mouse, you can send an email to another in a few of seconds, but is it easy to make its way from a sender to a recipient easily? The answer in a Mail Server. Mail Server is a computer that helps move email messages along to their intended destinations.
Mail servers show into two main categories: outgoing mail servers and incoming mail server.
Outgoing mail servers are known as SMTP, and Incoming mail servers come in POP3, or IMAP. All message operations are done by Mail Server.
When you press the “Send” button in your e-mail program (e-mail client) the program will connect to a SMTP server.
SMTP used when e-mails are delivered from clients to servers and from servers to other servers.
The recipient’s SMTP server scans the incoming message. If it recognizes the domain and the user name, it forwards the message along to the domain’s POP3 or IMAP server, at that point, the message can be read by the recipient.
