What is IMAP?
IMAP means “Internet Message Access Protocol”, this as the POP is a mail protocol. IMAP protocol allows users to connect from many different mail applications or webmail and different devices and see the same emails, as these maintained at all times to the email server, until the user deletes them.
IMAP protocol follows the following steps when receiving mail from the mail server:
- Server connection
- Downloads the content requested by the user and temporarily stores it locally, eg. list of new mails, message summaries or the content of selected messages
- Edit all user options, such as marking messages as read, deleting messages and other
Note: the structures of folders and emails stored on the server, while locally preserved only copies which are usually stored temporarily.
