Criminals have been using FORGED return addresses for years, including some of ours at Guenther.com. Among them is (info @ guenther . com). This is NOT a legitimate return address. Any email FROM that address is a criminal SPAM with a FORGED return address! Any email TO that address will disappear into a black hole. More information about this problem.
We at Guenther Publishing regret, that our name has been used by spammers, but hope you will understand, that we have no control over this criminal activity.
