OPSSQL GNR Server Email Gateway v 1.3.1 or higher can be configured to send email via servers that require SMTP AUTHENTIFICATION.
To turn on this capability, you need to add the following lines into your GNR.INI configuration file:
SMTPAUTH = 1
SMTPUSER = username
SMTPPASS = password
where username and password are strings that contain the account username and account password assigned to you by your email server administrator.
