Setting email header to objective-C?

I am trying to create an application that sends an email using MFMailComposeViewController , but this class does not seem to be able to set email headers.

I tried to find a lower level solution (or even a library) that does this, but cannot find it. How to set up / get email headers in Objective-C app?

[EDIT] To be clear, I am looking for a way to set email headers in ways other than MFMailComposeViewController. I already know how to send a simple email. I am looking for a way to set email headers such as In-Reply-To or Message-ID

The authors of Sparrow created a great class called MailCore (now with version 2) that allows you to do just that.

If you go to class class documentation here: http://libmailcore.com/mailcore2/api/Classes/MCOMessageHeader.html

You can find all the useful headers in properties like messageID , inReplyTo , etc.

If you want to create an email header, you can create your own custom header using html and set it as the body of an email message with isHTML as True.

I just tried the following code:

 NSString * Htmlstr =[NSString stringWithFormat:@ "<html>" "<body>" "<div id=\"container\" style=\"background-color:#EEEEEE;height:300px;width:500px;float:left;\">" "<div id=\"header\" style=\"background-color:#FFA500;\">" "<h3 style=\"margin-top:0;\">ABC</h3></div>" "<div id=\"content\" style=\"background-color:#EEEEEE;height:300px;width:500px;float:left;\">%@</div>" "<div id=\"Banner\" style=\"background-color:#EEEEEE;clear:both;text-align:left;margin-top:0;\"><img src=\"%@\" alt=\"Smiley face\" width=\"500\" height=\"100\"></div>" "<div id=\"footer\" style=\"background-color:#FFA500;clear:both;text-align:center;margin-bottom:0;\">Copyright © abc.com</div>" "</div>" "</body>" "</html>",emailBody,self.SelectedBannerImage];

[mailer setMessageBody: Htmlstr isHTML: YES];

Hope this helps you.

I think you will have enough resources if you use the libcurl (c) library or one of its cocoa shells, no?

Check here BBHTTP and CURLHandle .

This will allow you to manually compose your smtp traffic using the cocoa / objc syntax. Does it look more like what you are looking for?
