I did explain that taht sympa do not manage check point a few days ago :

Currently, if you want to do it how to do it "by hand" :

   * dump the related list running sympa --dump <listname>
   * configure the list to have the higher priority because in case of
     a crash/restart you will be unhappy if some
     subscribtion/unsubscribtion in the list occurs before the
     distribution task is finished.
   * run sympa.pl using option "-m", it will log each subscriber email
     when broadcasting the message. 
   * If a crash occurs (it should not !) : write a small awk/grep/perl
     script that remove each subscriber where his email as been logued
     by sympa then retart Sympa and send a "kill -TERM" as soon as the
     distribution restart.
   * When the distribution is finished, sympa will stop (because the
     TERM signal) so you can restore the subscriber list before some
     subscribtion/unsubscribtion occurs.

We did it a very long time ago, and it works but  for a long time now we 
ignore sympa crashes :-)

We have added "check point and restart"  in our TODO, it will be very 
easy to introduce it in Sympa.
