Dear PKT If rename the folder mailroot any problems may araise ? regardsRaSa

There is probably no reason to do that. How do you know you are relaying SPAM?

Hi Rasa, Generally, there should be no risk to rename this folder. When message arrive in Exchange server 2003 through SMTP, the data is written to a file in NTFS file system (specifically, an .eml file). By default, thses files are written to a directory (<drive>:\Program\Exchsrvr\Mailroot). As you can see there are three folders by default in this folder, the BadMail folder contains undeliverable emails, the PickUp folder is a temp folder for SMTP virtual server to deliver, the Queue folder contains emails that cannot be delivered and keep retrying. If Exchange mailflow is correct, the three folders should be empty. In some scenarios, such as when you configure a bridgehead server, you can improve the performance of Exchange 2003 computer if you move the Mailroot folder to a different hard disk. If you would like to rename it, please stop the SMTP service before the rename action. Then after you start SMTP service, Exchange server will re-create a new one. How to Change the Exchange 2003 SMTP Mailroot folder location: http://support.microsoft.com/kb/822933/en-us In addition, for preventing open relay, you can refer the document provided by Andy. Hope it helps. Best regards, Serena

Yes, but I see no evidence that renaming the SMTP folders is even required yet.
