How do I specify an SMTP server after installation?
eHealth 6.3.x and above
Microsoft Windows (all supported versions)
Set the NH_NT_SMTP_SERVER environment variable to the hostname or IP address of a valid SMTP server.
Note: There is no need for an additional mail utility to be installed, but eHealth server processes will need to be stopped and restarted for any changes to take effect.
Refer to How to Set Environment Variables on NT for more information.
