Display Gmail, Yahoo or any other mail list in codeigniter Application.

Yes, it's possible. Check PHP's imap extension: http://php.net/manual/en/book.imap.php

Thanks josepostiga

can you provide a more information on it.

Like live example.

I don't have a live example. Try going through the imap functions and read the docs. I'm sure you'll be able to create what you want in no time! Start with this: http://php.net/manual/en/function.imap-open.php

Thanks Josepostinga
