Warning - identity theft

Dear Friends
I have been informed that some of you received e-mails containing advertisements or proposals coming from the following e-mail addresses:
gtomezzoli@2n4xul.77.msg-serice19.ru
gtomezzoli@k23z507b.msg-service18.ru .
Because I am not the author of such e-mails, this is a clear identity theft. Thus, I suggest you to not accept e-mails coming from said e-mail addresses or similar.
Salutations
Giancarlo
