Answer 4

SMTP sends mail.

POP3 retrieves the mail to your local server but will allow you to keep the messages on the server for x days.

IMAP also retrieves the mail but typically the mail stays on the server and your computer reads the server for each message instead of downloading the messages. However, outlook tends to cache the messages locally. Not sure about other softwares. IMAP tends to be slower than POP3 because it downloads all the message headers each time you connect then downloads the message when you click on it. Some companies prefer this option so messages can be backed up on the server.
