What is IMAP? IMAP is short for Internet Message Access Protocol, so like the previous TelNet program we are again speaking of protocols here. The IMAP protocol is used basically for monitoring and accessing your email and your email messages.
The latest IMAP is IMAP 4 and its function lies in checking and viewing your e-mail message. The way IMAP protocol is configured is that it’s a client/server protocol.
Now this means that when an e-mail is received on your e-mail address, you can see who sent that e-mail to you and the heading of the e-mail (or the subject). This is how you can choose to download the e-mail files attached to it or you can click and view the e-mail message that it has been sent to you.
That is why the IMAP has “access” in it. While you are using your mail through the IMAP protocol you may as well manipulate with folders and files, download them, put them in another folder, delete them and so on.
You can also put keywords in a search bar and look for a particular e-mail message. This is why IMAP is more sophisticated than POP3 (Post Office Protocol).
