IMAP is a great option for:

Synchronous access to all email accounts on all devices

POP3 has some disadvantages:

Downloaded copies of your emails can be saved on a single device

POP3 does not synchronize the emails and their changes across your devices.
Data loss is a greater risk with POP3 email accounts.

You should choose Rediffmail IMAP settings over POP3 settings every time.
