E-mail messages arrive at a server and then a client
accesses them
Client using POP3 protocol connects to internet,
downloads the mails and then reads them later on.
Client using the IMAP protocol connects to the internet
and reads the messages while connected
An e-mail client is a stand-alone program
When the e-mail client is a web page it is web-based
email
User can configure an e-mail client to use POP3, or
IMAP, or both
