Thanks.  I know about heartbeat but for some reason did not think of it
in this context. I will certainly look to implement it.

I still have to find the correct tool to replicate the
postgresql-tables.

How do you configure the setup on the second server to disallow the
administration of the lists?  Is removing the task_manager daemon
enough?

Unfortunately DRBD is not an option for me as the as both the master and
slave sympa servers are active mailservers at the same time which and
the postgresql-database is also used by exim.  Is thus not just a case
of duplicating a block device.

Anyhow you have opened my eyes for some options I did not consider.
Thanks for that.

Regards
Johann
