Email to myself from address book contacts.

Hi-

I am receiving emails from mt address book contacts that have contacts' name but various nonsense Yahoo addresses.  They all have the heading "To <my name>" or "Hi <my name>".  None of the contacts report receiving spam from my address.

 

Scans with NIS 2013 have found nothing.  The emails all have a link in them (which I haven't opened, of course).  Here's an example:

The "To:" is my email address.  The redacted top portion is a contact's name.

 

Any thoughts?

 

Thanks
