These posts are about ten years old, yet we still keep receiving boxtrapper spam.

We list it as spam. False accusations about forged sender addresses having sent spam are the only type of spam we list that isn’t Scientific Spam proper. This software (these types of software, including Spam Arrest, misconfigured amavisd-new, etc.) should simply not exist at all.
