3. Objective
•The email client connects to the SMTP server.
•The SMTP server identifies and processes the recipient's email address,
the body of the message and additional attachments.
•If the domain name is the same as the sender's, the message is routed
directly over POP3 or IMAP.
•If the domain name is different, the SMTP server communicates with the
domain name system (DNS) to find the recipient's server. The DNS translates
the recipient's email domain name into an Internet Protocol IP address.
•The recipient's IP address connects to the SMTP server. Once the IP is
identified, the sent message is routed between unrelated SMTP servers until it
arrives at its destination.
•The recipient's SMTP server handles the email. It checks the message and
directs it over to an IMAP or POP3 server. The email is then placed in a mail
queue until the recipient retrieves it.
