Internet Message Access Protocol (IMAP) is an incoming server used by the customers of Comcast emails. Its main function is to save email messages on a mail server (locally on the device) and allows the receiver to view and edit it according to their needs.

However, IMAP has more advanced features than the POP3, as it gives permission to multiple devices to use the Mailbird at the same time; it also asks you every time before deleting any email. At the same time, POP3 doesn’t ask you for permission to delete emails from the server.
