Hi,
1. Open SQL Server Management Studio
2. In the Tree menu (Left side of the screen) expand 'Management'
3. Right click on 'Database Mail'
4. Select 'Configure Database Mail'
5. if this is the first time you are setting up choose the first option
ie 'Setup Database mail performing the following Tasks...'
if Database mail is already setup choose the second option namely the
'Manage Database mail accounts and profiles'
Follow the prompts and you should be good. When prompted for SMTP server
enter your server IP. I myself use an exchange server.
Hope this helps
Thanks
