The MX record lookup can return one or more destination MTAs. This DNS record is known as the MX record. When an MTA needs to verify where to send an email, it performs a lookup for a specific type of DNS record on the domain portion of the recipient’s email address. A mail server may also support MTA functionality.ĭNS plays an important role in email delivery. A mail server is the final destination of an email before the recipient retrieves it. Open relays are widely exploited by spammers, to send unsolicited spam in bulk. MTAs that don’t implement these mechanisms are referred to as open relays. This can be in the form of authentication or filtering rules, based on source IP. Typically, MTAs implement a vetting mechanism to check if a sender is authorized to use the services of that MTA. FortiMail in server mode is both a mail relay and the destination server. FortiMail operating in gateway mode is a mail relay. Mail relays can exist internally, on an enterprise network, or on the Internet, provided as a service by an ISP for its customers. An SMTP server that handles email, but isn't the final destination server, is an MTA (also known as a mail relay). MUAs facilitate email retrieval using protocols, such as POP or IMAP. By demonstrating competence in SMTP and DNS roles, you will be able to identify SMTP roles and understand the importance of DNS in email exchanges.Įnd users interact with SMTP using an MUA, such as Outlook, Thunderbird, or Apple Mail, to compose and send email. In this lesson, you will learn about the topics shown on this slide.Īfter completing this section, you should be able to achieve the objectives shown on this slide. In this lesson, you will learn about basic email concepts and gain an understanding of SMTP and FortiMail.
