What is an SMTP server?

SMTP or Simple Mail Transfer Protocol is the procedure that directs the email flow over internet. It's primary purpose being to send, receive and/or relay emails between senders and receivers.

An SMTP server has an address(or addresses) which is set by mail clients (generally formatted as smtp.serveraddress.com). The SMTP server address can be found in the accounts or settings section of the mailing application you are using.

When you send an email, the SMTP server processes your email, deciding which server your message will be relayed to. Following this, the recipients' mail client downloads the message from the server and places it at the desired place in the inbox.
