Summary
In this chapter, we have gone over standard email protocols; the system uses SMTP for sending emails, while POP and IMAP are used for receiving emails. IMAP also includes features that can be used to manage the user's inbox. We went over the email header and the components that make up the header. WebMail and email clients were also discussed.
You now have the skills necessary to read an email header and determine the servers that were used to transmit the email, as well as what protocols the system used to send and receive the email. When conducting a digital forensic examination, you can now identify artifacts from typical email clients and web-based email.
In the next chapter, you will learn that some web-based emails have similarities among them.
