I want my app using the MFMailComposeViewController to send an email such that the recipient can click on the embedded url to open the corresponding web site. MFMailComposeViewController does not appear to support this explicitly. Any ideas?

I deleted my previous answer as it was incorrect and irrelevant. After much hair pulling I finally figured out what was going on in my case and is probably what is happening in this question.

When you compose the HTML body for the MFMailComposeViewController you must put line breaks in the HTML. If any line is > 76 chars long, the body will be interpreted as follows:

Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

If you put line breaks in, the Content-Transfer-Encoding: quoted-printable will not happen and everything works as expected. Assuming you have proper HTML.

As an example, build the body as follows:

NSMutableString *body = [NSMutableString string];
// add HTML before the link here with line breaks (\n)
[body appendString:@"<h1>Hello User!</h1>\n"];
[body appendString:@"<a href=\"http://www.mysite.com/path/to/link\">Click Me!</a>\n"];
[body appendString:@"<div>Thanks much!</div>\n"];

Cheers!
