  1. What is your preferred electronic mail address at Bendigo? In general, what is the format of an Internet email address?

  2. What is the general format of an RFC822 electronic mail message?

  3. The DATA operation in the SMTP protocol uses a "." on a line by itself to indicate the end of the mail message. What do you think happens if this occurs in the message?

  4. The SMTP protocol, like the FTP protocol, uses a 3-digit code in all communications from the server. From the example given in the lecture, can you generalise about the significance of the first digit of this code? What about the second digit?

  5. What is MIME? Explain briefly how MIME works to send a file (eg, a GIF image) as an email message. What is a MIME Multitpart message?

  6. What is the Post Office Protocol (POP) used for?

  7. In the SMTP protocol, the sender uses the "Rcpt to:" operation to specify the mail destination. What do you think happens if this is different to the "To:" address in the message itself?
