  brief introduction

  Hello altogether,
  after I broke my first keyboard (delete-key was broken due to SPAM-deletion) I deciced to think about. ;-)
  
  Perhaps somebody else knows smtpd from Obtuse.com (debian: apt-get install smtpd).
  I got to know this funny nice tool some years ago, maybe 2000. It runs in a chrooted environment, it's started from xinetd provided with some parameters and only fetches mail to put it into a file on the disk. Intended to work with an antivirus solution like clamav, it's only something around 75k bytes of C, so one is able to read it all. Its written in a really paranoid manner, so I liked it from the first glance. It's most favorite feature is a nice configurationfile to contain which email adresses we like, from which ip-addresses and, of course, those we don't like, too.
  
  I added some lines of C, some new config files like black- and white-list, a greylist, which is written by the program itself. Later I added a configfeature for varying the greytime on the commandline and fixed a bug (long int to unsigned long int). Of course, its not free of costs. For the first mail from a sender, you have to wait for his retries as long as configured.
  
  Thank you for your reading,
  greetings from Cologne, Germany, Europe.
