I’ve seen some custom libraries for sending e-mails, but are there any available for receiving them? I know of numerous ones that are available for the mac, but not for the iPhone – and I mean, MobileMail.app must do it somehow 😛
Has anyone got any ideas on this?
You can port most any POP or IMAP client code that can run inside a single process… however an app on a stock OS device is sandboxed off from the email credentials that a user enters in the Settings app, so an app will have to ask for its own email login credentials and do its own email protocol handling.
Apple also seems to reserve the right to reject apps that merely duplicate the built-in Mail app.
