Kolab multi-master setup

[kaspro at web.de]

Hi there,
I wonder whether there is - additionally to the master-slave setup a possibility to sync mails from one- to another server. This would be helpful in case that the internet goes down, one can still send/receive domain-internal mails, send calendar requests etc. if the actual kolab server sits on the internet... LDAP could stay in master-slave setup- just mails and notes/calendar entries would be interesting...
Any ideas on that?!

Thanks all in advance,
Cheers Chris
