If you recieved spam-emails from some senders like 'qkdfbhwr@heavylounging.de' or similar,

these mails were not sent from this domain!

It is a case of "address-spoofing", which means someone sends emails over an open mail-relay and fakes the sender address,

that it seems as if the mails came from the domain "heavylounging.de".

In fact, the mails are sent from some server in mexico or somewhere else in Central-America.

I did write "abuse" emails to the administrators of the servers, but so far without any success.

I am as annoyed as you are (I recieve about 100 mails per day concerning undelivered mails) - so please stop to send viruses etc. in reply.

Thank You!
