     Topic:  The PostFix Mail Server  

   Speaker:  Wietse Venema  

  ** H A P P Y   N E W   Y E A R **


  Wietse Venema is known throughout the world as the author of popular, freely
  available Security Tools 
  such as Satan (co-author), TCP Wrappers, Portmap and LogDaemon.

  Postfix was written by Wietse Venema in an attempt to provide an alternative
  to the widely-used Sendmail  program.  Postfix
  attempts to be fast, easy to administer, and secure, while at the same
  time being sendmail compatible enough to not upset existing users.

  Postfix is said to be up to three times as fast as its nearest competitor
  [I'm guessing this means qmail ], which means a
  desktop PC running Postfix should be able to receive and deliver a million
  different messages per day.  Postfix uses web server tricks to reduce
  process creation overhead and uses other tricks to reduce file system
  overhead, without compromising reliability.

  Note that Postfix used to be called VMailer.

  Description of Talk: 

  PostFix - What it is and what it does.

  Speaker Biography: 

  (Autobiographical, Extracted from Mr. Venema's Web Page)

  Previous life:

  In a previous life I studied physics at Groningen University in the
  Netherlands, where I also did my Ph.D. dissertation. 

  Then I spent 12 years at Eindhoven University, also in the Netherlands,
  as systems architect at the Mathematics and Computing Science department. 

  For 10 years, part of that university time was devoted to writing tools
  for automated translation of EDI (Electronic Data Interchange) messages.
  First with Nedlloyd, then with Encompass (now Calixon).  This is the
  best software that I have written so far. 

  Current life:

  Most people know me from software that I wrote to protect systems
  against Internet intruders. This began in 1990 when Eindhoven University
  was connected to the Internet. 

  I have given away the programs that I use myself, so that other people
  can inspect them, and can use the programs that they trust.  By now,
  this software has an installed base of millions of systems.

  I am continuing this tradition with IBM, at the Thomas J. Watson
  Research Center, in the USA.  The first result is Postfix.  This is
  mail server software that is fast, easy to configure, and hopefully
  secure.  I wrote it for those who seek an alternative to the
  widely-used Sendmail software that delivers billions of email
  messages daily. 


  Complimentary Refreshments will be served.


     55 Water Street is between Water Street & Front Streets at Old Slip...
     about 7 blocks south of Fulton St. and the South Street Seaport.
     Take 4 train to Bowling Green & Walk Due East;
     Take 2/3 trains to Wall Street, Walk East to Water St.
          then walk South 5 blocks;
     Take M/J trains to Broad St., Walk East to Water St.;
     Take N/R trains to Whitehall St., Walk North East to Water St.
     There is parking on the street (after 6:30-7pm) and there is a lot
          right in the building, entrance on Old Slip.
     Walking from Wall St., follow William St. south which bends around
          and leads you to Hanover Sq. and Old Slip is across Water Street.

  Room Location Specifics:
     Enter the building at Old Slip.  To get to the South Tower of the
     complex, you enter the building at Old Slip at the "North Tower"
     doors.  This entrance is is immediately to the right of the main
     entrance, towards Water Street.  Go past the guard's desk (mentioning
     you are heading for Unigroup) to the elevator bank and go to the 13th
     floor.  When you get to the 13th floor, follow the signs leading you
     to the meeting room.

     The signs will lead you from the elevator, through a set of doors
     (soda machine will be on your left), then past the cafeteria.  After
     the cafeteria, you see another "lobby" area.  Walk past the cash
     machines, make a left and look for a sign marking the meeting room.
     Conference Room C will be on your left.

     If you come very early, we may not have the signs in place yet, but
     hopefully these directions will get you to the meeting room.
     If you arrive before Unigroup Board Members, please be patient and
     wait for us to arrive.  The building cafeteria is open to the public.
