You might have thought that the Mail.app included with OS X might have a hunch that e-mails from Apple (specifically from apple.com) probably isn’t going to be a spammer.
True you as a user may mark e-mails from Apple as junk manually, but the automated process, nah!
Or so you would think!
A few days ago I “purchased” a fair few apps from the iTunes store and as per usual Apple sent me a receipt outlining my purchases. I have received many of these not just because of the stuff I buy, but also as I more often then not download the free single of the week as well.
So you can imagine my surprise when Mail.app marked my latest receipt as junk!
No idea why.
