Just set up my iCloud account and was given the email@example.com by default. I thought I would try and test this address and sent a few emails to it. As time went by I was still waiting to see these test emails and still received nothing. The next day I receive an email from a person with the same icloud address that I was given, telling me that he has this already!
Rather confusing so I have had to set up an alias to get round the problem. Question is as my title says...why give me this address in the first place?
