Unfortunately, in the recent past spam mails with fake sender addresses have increasingly been sent in the From header (sender information).
For some time now, (fictitious) addresses from our domain have also been abused for this purpose. If you have received SPAM mails with sender details from our domain, please do not send your complaint to us or our provider.
Like many of those affected, we are not responsible for sending these mails and unfortunately cannot prevent them. The hitherto hopeless fight against spam mail now occupies governments and international organizations.
If you have a complaint, you should carefully check the email header files. Unfortunately, the From header can often be entered at will and does not allow any conclusions to be drawn about the true sender.
