If you have received SPAMS from Kadrane, please accept my apologies. It is totally independent of my will. These emails are not generated from the Kadrane's computers that are running under Linux and whose anti-virus are daily updated. Unfortunately Kadrane email address is stored in databases used by viruses. In theory, it is impossible to stop it.
If you are victim of SPAMS from Kadrane, please forward the SMTP headers to email@example.com. I can not promise that I will stop it, but, in some cases, it is possible to identify the IP address from which the emails have been generated. In such a case, I can contact the ISP to remove the virus.
