Got an email this morning - both the subject and body said:
It was from someone I've never heard of,
To someone (one email address) I've never heard of,
And, both in Outlook 2013 and on my iPhone I could see the BCC*, and that was (just) me.
There are no attachments or links in the message.

*maybe that's normal behavior - if YOU are the recipient of a BCC you can see it?
Please ignore if you receive this unexpected email!
