i Knew abt the Yahoo pops thing frm KS long back, to be exact an yr ago..
now i got the actual working of it from Paramaguru, who joined Tech_here
recently. Its easy and here is the extract from his post…

How it has been done :

Well, this application is more like a gateway. It provides a POP3 server interface at o­ne end to talk to email clients and an HTTP client (browser) interface at the other which allows it to talk to Yahoo.Thanks Paramaguru for posting this info…:)
