Hello everyone, I would like to please support me with the following, I have currently installed a Windows Server 2003 R2 Enterprise SP2, in that I have installed Exchange Server 2003 Enterprise SP2, now I can send and receive emails internal and external with no problems. In addition to spam filtering appliance I have installed a Barracuda Spam Firewall 300. So that it can filter incoming and outgoing SmartHost I have configured on the SMTP protocol and the connector on the Routing Groups. And as I return to mention I can send and receive email filters through the barracuda just described that I can verify in the logs of emails sent and received from the appliance. The problem I have is that for some reason the emails sent and received internally, I mean an internal user mail to internal user 2, are not being filtered by barracuda, this was indicated because of logging messages barracuda these do not appear, so I would like to indicate if any additional configuration to be made at the exchange server. I've heard suggestions that there is an article in which he describes to be made any amendment to the logging level mail server for the analysis of internal mail can be filtered by barracuda, but have not found it and I would like you me confirmation of that item or indicate that other configuration is necessary for this to be implemented and in turn is running the internal mail filtering. I appreciate the attention brought to this post and I look forward to your comments. Hamilton Snchez

Messages between mailboxes in an Exchange organization are not sent to (or through) any external servers. [ snip ] --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Thanks for your response. So to conclude, emails sent and / or received internally within the organization are made at the level of exchange databases AND NOT out to the internal network and then to the destination mailbox. For that reason the mail Not through the barracuda. Hamilton Snchez

Messages between servers within the same Exchange organization are either sent directly between servers in the same Exchange Routing Group, or (most usually) between Routing Groups using Routing Group Connectors (which use local and remote bridgehead servers). Messages between mailboxes on the same server don't use your LAN to move the messages between mailboxes. >AND NOT out to the internal network and then to the destination mailbox.

Mail within the Exchange organization will not pass through your spam filter. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Hamilton, Agree with Rich, I have run into the same scenario, and use the barracuda as an spam filter too, it just filter the inbound and outbound mail of your exchange ORG. But, per my known, if your have multiple sites, and each site have exchange server, you could use barracuda as spam filter SMTP gateway, if you just have one site and only one exchange server, there is no way filter the email by barracuda.
