I know there is no method in iOS for setting the From: address header in MFMailComposeViewController http://developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMailComposeViewController_class/Reference/Reference.html#//apple_ref/occ/cl/MFMailComposeViewController.
However, I can't believe it is not possible since iOS version 3.
Is there any offical way in iOS to configure the MailComposer with a specific mail account?
The business requirements for the app are: Send email using a From (or reply-to) address depending on some recipients properties.
