What kind of strange spam is sent to mail.ru if the body of the letter does not contain my email address at all?

Question

Fight against spam

I just received a letter to one of my oldest mailboxes on mail.ru (that's why there is a lot of spam falling in there but it is not bad cut off by automatic spam filters, but not this one), and my eye caught on the address in the 'to' field - [email protected] , this is not my address and I don't have such aliases:

Probably rhetorical questions about the sender of this spam can no longer be asked?

Answer 1

Looks like your address was in the "Bcc" field. We always get stuff like this in our work mail.
