What is an SMTP (Outgoing Mail Server)?

THE SMTP protocol (Simple Mail Transfer Protocol) is the standard protocol that allows e-mail to transfer from a server to another connection.

It is about a protocol that sends mail traffic immediately to another server. The SMTP Protocol works with a few text commands that are being sent to the SMTP server (default is this gate 25). Each send command is being followed by an answer of the SMTP server.
To be able to send mails, you need to configure the SMTP of your internet provider in your mail program (Outlook, Thunderbird, ...)
