How to send emai using SMTP server in iphone sdk without using Composer Window?

Here In My app, There is a case where User registering a form He will give his mail id in one textfield. After Complete the开发者_Go百科 form I need to send a mail to User for conformation of his registering.

Any one can help me please.

Thanks In Advance

I don't think its the right way to send email from the phone to the user's email id. You need to process the form at a remote server and it should send the confirmation email which most of the phone apps with user registration do. If you are going to save the user data locally, there will be several problems and the top problem would be rejection of the app from apple.

actually its pretty simple, you just have to connect to mail server and send commands
