I’m gonna run a so called master-master replication between the 2
servers. Meaning any change in the tables will be instantly replicated to the
other server, so should one go down the chance of data loss is very slim.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Regarding the quarantine I also need some more or
less complex solution, since I don’t want to use local quarantine
directories for each server. The reason is that I do NOT want a local
quarantine directory on each server. I do not want that because then I do not
have access to release mails quarantined by the server that is down (Even if if
setup some rsync script it isn’t real-time so data loss is very likely)
There for I plan on using a system like drbd (<a href="http://www.drbd.org/"
title="http://www.drbd.org/">http://www.drbd.org/</a> ) or another similar
distributed file system. That means you get a so called “network raid
mirror” where all disk io is replicated across a network so if 1 server
fails all data is still accessible on the other machine. This would enable me
to never loose the ability to release quarantined mails.<o:p></o:p></span></font></p>
