Query SMTP settings when sending email

You can query the Relativity database for SMTP server settings by using the Relativity API Helpers from an extensibility point. Use this functionality when sending email from agents, custom pages, or event handlers in conjunction with the .NET mail interface as illustrated in the following code sample.

Note: This code sample uses the IInstanceSettingsBundle interface available in Relativity 9.6.134.78 above.
