I have a newly installed exchange server on sbs 2003 R2 with all service packs and updates.
Exchange works fine for receiving email from the LAN, and from the internet for all accounts, except for the Administrator account. This account can receive email from within the LAN just fine, and can send mail to both LAN and internet.... from this account.
BUT - it can not receive outside email. When a user tries to send email to this account, they get a smtp rejection - not a valid user. All other user accounts work just fine. Any ideas?
Thanks a lot.
