A few things I d like to add here    Using the mailto URL won t work in the simulator as mail app isn t installed on the simulator   It does work on device though  There is a limit to the length of the mailto URL   If the URL is larger than 4096 characters  mail app won t launch  There is a new class in OS 3 0 that lets you send an e-mail without leaving your app  See the class MFMailComposeViewController

If you want to send email from your application  the above code is the only way to do it unless you code your own mail client  SMTP  inside your app  or have a server send the mail for you   For example  you could code your app to invoke a URL on your server which would send the mail for you  Then you simply call the URL from your code   Note that with the above code you can t attach anything to the email  which the SMTP client method would allow you to do  as well as the server-side method

On iOS 3 0 and later you should use the MFMailComposeViewController class  and the MFMailComposeViewControllerDelegate protocol  that is tucked away in the MessageUI framework   First add the framework and import    import  lt MessageUI MFMailComposeViewController h gt    Then  to send a message   MFMailComposeViewController  controller     MFMailComposeViewController alloc  init   controller mailComposeDelegate   self   controller setSubject   My Subject     controller setMessageBody   Hello there   isHTML NO    if  controller   self presentModalViewController controller animated YES    controller release     Then the user does the work and you get the delegate callback in time   -  void mailComposeController  MFMailComposeViewController  controller             didFinishWithResult  MFMailComposeResult result                          error  NSError  error      if  result    MFMailComposeResultSent        NSLog   It s away            self dismissModalViewControllerAnimated YES       Remember to check if the device is configured for sending email   if   MFMailComposeViewController canSendMail          Show the composer   else        Handle the error

On iOS 3 0 and later you should use the MFMailComposeViewController class  and the MFMailComposeViewControllerDelegate protocol  that is tucked away in the MessageUI framework   First add the framework and import    import  lt MessageUI MFMailComposeViewController h gt    Then  to send a message   MFMailComposeViewController  controller     MFMailComposeViewController alloc  init   controller mailComposeDelegate   self   controller setSubject   My Subject     controller setMessageBody   Hello there   isHTML NO    if  controller   self presentModalViewController controller animated YES    controller release     Then the user does the work and you get the delegate callback in time   -  void mailComposeController  MFMailComposeViewController  controller             didFinishWithResult  MFMailComposeResult result                          error  NSError  error      if  result    MFMailComposeResultSent        NSLog   It s away            self dismissModalViewControllerAnimated YES       Remember to check if the device is configured for sending email   if   MFMailComposeViewController canSendMail          Show the composer   else        Handle the error

A few things I d like to add here    Using the mailto URL won t work in the simulator as mail app isn t installed on the simulator   It does work on device though  There is a limit to the length of the mailto URL   If the URL is larger than 4096 characters  mail app won t launch  There is a new class in OS 3 0 that lets you send an e-mail without leaving your app  See the class MFMailComposeViewController
