I am hoping that somebody on this list is in regular contact with "Joerg Arndt" <arndt@jjj.de> and, if still able to reach him, would be kind enough to advise him that my replies to his emails are being blocked by rogue anti-spam software [apparently going under the name "grey-listing", though in my case "grey-hair-causing" might be more appropriate].

Problem solved: I got your email to me and Chr. Haenel. Explanation here: http://en.wikipedia.org/wiki/Greylisting Specifically, grey-listing kicks in when my server crashes (this recently happened a bit too often; the machine is old and will get replaced this year). My (only) other email address is joerg.arndt@th-nuernberg.de However, I do not check this one regularly, and very much so in semester breaks. Best regards, jj
