What are the scenarios that can result from using SMTP protocol for delivering e-mail messages?
What will be an ideal response?
When using the SMTP protocol for delivering e-mail messages, any one of the following scenarios could result:
* The sending SMTP server contacts the recipient's server and sends the e-mail message directly.
* The sending server cannot contact the recipient's actual SMTP server for some reason and tries to contact and deliver the message to the recipient's first back-up server.
* The sending server cannot contact the recipient's actual SMTP server or its first back-up server. Thus, the message is delivered to the recipient's second back-up server.
* The sending server cannot contact any of the recipient's SMTP servers. In this case, the sending server will hold on to the message and try to resend it later. It will keep retrying periodically for a set period of time, such as five days, until it succeeds in sending it or returns an error message to the sender.
