iOS: How to know if a mail account exist

Question

For my app, I need to know if there's a mail account has soon as the app is launched. Is there a way to do that ?

I don't really know what canSendMail does but it does not seems to verify that.

Thanks

Answer 1

canSendMail is actually the right and only way to verify what you want.

if ([MFMailComposeViewController canSendMail]) {
    // device is configured to send mail
}
