I try to send an e-mail from an app with an custom Content-Type.

Any ideas how to do this?

So i like to change

"Content-Type": "multipart/mixed; boundary=Apple-Mail-1--209662383" --> "application/pkcs7-mime; name=smime.p7m; smime-type=enveloped-data"

and "Content-Transfer-Encoding":

"7bit" --> "base开发者_Python百科64"

I used http://code.google.com/p/skpsmtpmessage/ for sending an custom mail with iOS.

• (void)launchInAppMail {

  MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];

  controller.mailComposeDelegate = self;

  [controller setSubject:@"In app email..."];

  NSMutableString *messageString = [[NSMutableString alloc] init];

  if (!(mNameField.text == nil || [mNameField.text isEqualToString:@""])) {

  [messageString appendFormat:@"Name: %@ \n",mNameField.text];
  

  } if (!(mPhoneNumberField.text == nil || [mPhoneNumberField.text isEqualToString:@""])) { [messageString appendFormat:@"Phone Number: %@ \n",mPhoneNumberField.text];

  }

  if (!(mEmailField.text == nil || [mEmailField.text isEqualToString:@""])) { [messageString appendFormat:@"Email ID: %@ \n",mEmailField.text]; }

  if (!(mTextView.text == nil || [mTextView.text isEqualToString:@""])) {

  [messageString appendFormat:@"Desription: %@ \n",mTextView.text];
  

  }

  if (!(mProblemNameButton.titleLabel.text == nil || [mProblemNameButton.titleLabel.text isEqualToString:@""])) {

  [messageString appendFormat:@"Problem Name:  %@ \n",mProblemNameButton.titleLabel.text];
  

  }

  [messageString appendFormat:@"Address: %@ \n", self.mAddress];

  if (self.coordinateLoc)

  [messageString appendFormat:@"Longitude: %f, Latitude: %f \n", self.coordinateLoc.coordinate.longitude, self.coordinateLoc.coordinate.latitude];
  

  [controller setToRecipients:[NSArray arrayWithObject:@"service@emergencylocksmithleads.com"]];

  [controller setMessageBody:messageString isHTML:NO];

  [messageString release];

  if (mImageView.image != nil) {

  NSData *imageData = UIImageJPEGRepresentation(mImageView.image, 1);
  
  
  [controller addAttachmentData:imageData mimeType:@"image/jpg" fileName:@"example.jpg"];
  

  }

  [self presentModalViewController:controller animated:YES];

  [controller release]; }
