“I’m not sure why, but in the last couple of days I’ve received several spam messages via my iCloud account. The messages are so obviously spam I don’t know why Apple hasn’t caught them. I know I can delete the messages, but is there anything I can do to let Apple know about this stuff?”
You’re not alone. I, and many people I know, have been hit by this wave. Fortunately, you have some recourse.
First, if you access these messages via iCloud webmail and then mark them as junk or drag them into the Junk folder, they’re automatically reported to Apple. To mark a message, go to www.icloud.com, log into your account, click Mail, select the spam message, click the Mark As pop-up menu and choose Junk Mail.
In Apple’s Mail application, you should forward these junky missives as attachments to email@example.com. To do this in Mail, just select the message and choose Message > Forward as Attachment. This generates a new email message that includes an attachment. This attachment contains not only the contents of the message, but also its headers – the information that details the internet path the message took to reach you. Apple uses this header information to filter out future messages sent from this vile domain.
Microsoft Outlook users can do this as well. In Outlook select the message and choose Message > Forward Special > As Attachment. Again, address it to firstname.lastname@example.org and send it.
Regrettably iOS’s Mail application doesn’t allow you to forward messages as an attachment.
