I have setup MS Exchange 2003 on a local network. I am running Small Business Server 2003 and exchange was installed as part of the package. All service packs and hotfixes have been applied.
The live sub-domain name for the shop is mbe.southbrisbane.com. The shop staff are members of a larger domain called mbe.com.au and have mailboxes with an external provider (Webcentral).
The internal DNS has records for both mbe.southbrisbane.com and also mbe.com.au.
The internal network is called mbe.local.
DEFINITIONS: "Internal staff member" implies someone who'se company email address is within my exchange server i.e. a local employee working within the local shop.
"External staff member" implies someone whose company email address is outside my exchange server i.e. an external employee NOT working within the local shop.
If an internal mbe staff member sends an email from their mbe.com.au email address to an external mbe employee to their mbe.com.au email address, then the email is rejected, as the receiver is not within the local usergroup.
If an external mbe staff member sends an email using his mbe.com.au email address to an internal mbe staff member to their mbe.com.au email address it is received without error.
Any other emailaddresses work bothways without error. The only ones that fail are ones sent to mbe.com.au email addresses from an external mbe.com.au email address.
Any assistance offered to allow local mbe users to send and receive email to and from other mbe.com.au email addresses would be appreciated.
I'm sorry if this a alittle too wordy .... but i need to be clear in my own head as to the configuration errors.
Thank you in advance.
