creating new mailbox on ispconfig 3.0.4.6 and master-slave configuration

[themark]

Hi there,

we have added on our stack a brand new server, in slave mode (we are in master-slave enviroment).

All works well, the only problem is that if I create a new mailbox, the mailbox will be created on the server, but added only in the master database (not in the slave). So postfix not see that the mailbox exist and so we are unable to send any email.

Any idea on what can happen there?
Thank you
