Mail sender Adapter (POP3,IMAP4)

Hi

I am trying to do Mail to FTP scenario.

In our PI system already SMTP Port :25 is opened and we are able receive alert emails to our inbox.

In my case, I want read mails from the inbox and send to FTP server.

-> shall I use SMTP to read mails from my inbox?

-> If so how i need to configure my sender mail CC (what is Tranport protocol..and URL format)

-> If not, How to configure POP3 or IMAP4 in my PI system.

I have all access of basis..I need procedure document to configure and open POP3 and IMAP4 protocols and ports(110 and 142)

people who has already done Mail sender scenario, please let me know how you configured your PI system to read the mails.

Thanks,

Murali.
