Making Exchange 2003 Use A Smart Host
Start the
Exchange System Manager. Navigate:
- Administrative Groups
- First Administrative Group
- Server
- $ServerName
- Protocols
- SMTP
- Default SMTP Virtual Server
Select
Properties, then
Advanced. You should find a
Smart Host field you can populate. The notes suggest that you put a name there so that if you need to logically move the relay it will be easy to change, however if you want an IP address you should surround it in [square brackets] so that the system treats it as an IP address and not a DNS lookup.
The typically unhelpful 'Help' lies to you about the navigation; it omits the first two steps.
