I got a call from my uncle today that the link in the email I have sent him did not work. I did not send him any email, so I have asked him to forward it to me. The email had my name, but came from other email address ***@lilac.ocn.ne.jp. That's not troubling much, however based on header info the same email has been also sent to few other people in my address book. I use multiple Gmail accounts where I keep the one with my contacts fairly isolated. I do not use it to sign up for anything, no sites, no forums, no newsletters, no look up my contacts to connect with people,... I have other dummy accounts for that, with no personal contacts. All my devices are personal and I do not log in anywhere else or use public WiFi. So how did someone get my contacts from my personal email account?
