Other tools from the author

  • Alternative libmilter - This is a modified libmilter using a pool of workers instead of one thread per SMTP connection. This allows to drastically reduce the number of threads in the filter : interesting if your server handles lots of simultaneous connections. This implementation of libmilter was integrated on sendmail 8.14.0 and received an Innovative Open Source Contribution award from sendmail.
  • Vigilog - a set of perl scripts to process Cisco Routers log files and detect scans.
  • j-sophosd a daemon virus scanner using Sophos savi library (not included) to use it with ze-filter release 1.7 and newers. This is a prototype.
