How to receive latest N message headers using IMAP

[harshavardhan Reddy <hvreddy1110 gmail com>]

Hi All,

Is there any way to only receive latest N mails from server using IMAP?

My idea is instead of receiving all the headers and updating in summary.mmap , I want to receive only latest N message headers. As you see the Gmail in Mobile platform, they will get only N messages initially and while the user scrolls down it fetches another N mails. 

I want to implement similar functionality.

Some idea or concept will be a great help.

I am thinking UID FETCH is there but am not sure to receive N messages...

Thank in advance.

Regards,
