Thanks a lot for your response.
My customer do not want to keep their mails on server, that's their policy, though I suggested them that was a bad idea. So I have to find out the best way to satisfy them.
Could you please tell me the way in details to: "configure the Replication so that Deletions and the ACL do not replicate". How to do it?
Thank you very much, Bob.
