{"ref":null,"ref_type":"repository","master_branch":"master","description":"ITC102 W16 - HW2: Email & DNS  Electronic Mail, or Email, is a transmitted message communicated over networks. The email is sent from an individual's email address, to a recipients email address via Simple Mail Transfer Protocol (SMTP). SMTP acts like the post office using the information you’ve provided to figure out where to send your mail. SMTP contacts a Domain Name System serve, or DNS, which acts like an address book that translates domains into IP addresses. Next DNS checks if the domain has a mail exchange (MX) server associated with it. If that mail box does not exist, a notification email will get bounced back to you. Assuming you’ve entered a viable email address, your email then goes to the target domains mail exchange server, or The Mail Transfer Agent (MTA). The MTA decides where to place your email, so that it’s available to be accessed by the recipient. ","pusher_type":"user"}
