Current setup: Windows Server 2000 with Exchange 2003 Server Enterprise Edition (in the process of upgrading to Windows Server 2003 Enterprise Edition). One subnet (192.168.0.x) of one local domain (bainet.local). Only one Exchange server in the single domain. The computer is shutdown every night to facilitate rebuilding a RAID array for backup. As a result we have an external email account which handles our email.
Employees connect to their external accounts using either Outlook 2000 or 2002 (planning on upgrading all to 2003). Email is downloaded from boughtonarchitects.com and stored in their personal mailboxes on the server. Everything worked fine when sending and receiving email (both external to the company through the internet email account) and when sending internal email with Exchange 5.5 but this is not the case now.
I'm not sure I understand SMTP connectors and virtual servers well enough to setup the appropriate relays. Some external email seems to come in and go out for some clients but not for others. When sending email out it comes back as a NDR since external SMTP clients cannot validate our internal domain (bainet.local). How do I set this up?
