MAIF: Mailing a Pure Spamtrap :(
MAIF, a French insurance company, is spamming an email address that has never existed at all. This email address is present on many lists for sale in countries whose primary languages are French, Italian, Portuguese, and Spanish, and receives a good deal of spam from otherwise legitimate companies in those languages. Their ESP is Mail Advantage, a subsidiary of CheetahMail, a subsidiary of Experian.
