Problem with Iphones

The problem is not with the iPhones.

The problem lies with the fact that you're not using AUTH when nowadays it's absolutely necessary.

You need to use AUTH, and SPF with hardfail as well. I also insert a custom header into authenticated users' e-mails so that SpamAssassin will score a -100 on them, and that helps a lot.
