Python provides a client-side library called imaplib, which can be used for accessing e-mails over the IMAP protocol. This provides the IMAP4() class, which implements the IMAP protocol. It takes two arguments, that is, host and port for implementing this protocol. By default, 143 has been used as the port number.
