I have just set up a new Exchange 2k3 in the same organization as my Exchange 2K. Everything I am doing now I have done in a practice setup and all worked fine. The new mail server joined the organization just fine.
The only problem that I have is sending mail from a MB on the new 2k3 server to a MB on the 2k server. The mail transfer hangs after the command
354 Send Binary Data
I verified this with SMTP logging and a sniffer from Ethereal.
If I send mail from 2K to 2K3 all works OK. I have seen threads regarding firewalls having problems with this SMTP command but this transfer does not occur through a FW. Both servers are on the same subnet. Transmission is from NIC to NIC.
This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.
