For the past two months, I have received many automated warnings that supposedly my mailserver was sending spam and/or virusses. It turned out quickly that the real sender of this junk is a T-Online user with a dialup account who sends out daily runs of probably his/her whole addressbook and sometimes spoofs the e-mail address I used to subscribe to this list. The person may be reading this list, so if your IP address today is 'pD951F606.dip.t-dialin.net[217.81.246.6]', you badly need to clean up your system. I has been sending virusses steadily since March 19th. I have sent numerous complaints about this to the abuse address of T-Online and T-IPnet already, with logfiles indicating the times and IP addresses from where the junk came from. To no avail, they have done nothing so far, other than complaining once about the encoding of the attachments, which they thought was base64 while in fact it was 7bit (readable in any mailreader). What other options do I have to stop this system for further distributing virusses? Best regards, Arjen
