we have the following configuration:

1 small business server
2 NICs
We have Groupwise 6.5 installed. We have a secondary ipaddress at the public and private interface for the mail service. When we send a test mail the recipient gets the mime information with the correct dns hostname record mail.xxxx.com but with the wrong ip address which is the primary ip address of the public interface. Any idea why it is always the primary public ipaddress that gets sent in the mime information can I change this somewhere at the bordermanager configuration?
