[mail setToRecipients:[NSArray arrayWithObjects:#"marketing#realestateinvestar.com.au",nil]];
//[self becomeFirstResponder];
mail.navigationBar.tintColor=[UIColor blackColor];
[self presentModalViewController:mail animated:YES];

Answer 1

if ([MFMessageComposeViewController canSendText])
Your problem is here. You are trying to check whether device will be able to send Text messages and not email Message. you should try using
if([MFMailComposeViewController canSendMail])
The problem might be that your device is not configured to any accounts in the mail.Please check this once.

Answer 2

Have you implement MFMailComposeViewControllerdelegate methods in your code??
#pragma mark --------------------------------------------
#pragma mark MFMailComposeViewController delegate Methods
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
switch (result) {
case MFMailComposeResultCancelled:
NSLog(#"Mail send canceled.");
/*
Execute your code for canceled event here ...
*/
break;
case MFMailComposeResultSaved:
NSLog(#"Mail saved.");
/*
Execute your code for email saved event here ...
*/
break;
case MFMailComposeResultSent: {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Mail Sent" message:nil delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
alert.tag = 1;
alert.delegate = self;
[alert show];
[alert release];
break;
}
case MFMailComposeResultFailed: {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Mail Sending Failed" message:nil delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
alert.tag = 2;
alert.delegate = self;
[alert show];
[alert release];
break;
}
default:
break;
}
[controller dismissModalViewControllerAnimated:YES];//dismissing modal view controller
}

Answer 3

Your code looks ok, but did you check if the device can send mail:
if ([MFMailComposeViewController canSendText]) {
MFMailComposeViewController *mail=[[MFMailComposeViewController alloc]init];
mail.mailComposeDelegate=self;
[mail setToRecipients:[NSArray arrayWithObjects:#"marketing#realestateinvestar.com.au",nil]];
mail.navigationBar.tintColor=[UIColor blackColor];
[self presentModalViewController:mail animated:YES];
[mail release], mail = nil;
} else {
// show message to the use that he can't send an email.
}
