Exchange 2003 migration to Exchange 2010 server
Exchange 2003 migration to Exchange 2010 server and Spam Filtering of SMTP IP Address I will be forwarding all emails this weekend to the new migrated Exchange 2010 server and the 2003 Exchange server will only substituting/proxying requests from the Exchange 2010 server. I have right now a Barracuda anti spam firewall installed in the 2003 server that has an IP of the 2003 server "destination Mail Server". Also, it is a receiving and sending IP.
Do I have to adjust this to the 2010 server? (I'm sure it needs some adjustment but I have to be sure to gather second opinion). Note: My Mailboxes are still using 2003 server but I want all the outgoing and incoming email messages course through the 2010 Exchange server so I wanted to know which IP will have to go into the Barracuda.
Please anybody help me with this matter, thank you in advance.
