write own mail client to send Mail using SMTP/POP3 server on iphone

I am trying to develop application to send mail using configured SMTP client rather than iPhone's default MailController开发者_Go百科.

How can i implement this functionality? Is it possible to design such client?

Thanks,

Jim.

It is possible, however, unless you want to develop your own implementation of the protocols and start opening TCP ports, etc, you might want to look into OSS tools that provide these features.

this might help you out.
