How to configure SMTP setup
Tableau Server can email server administrators about system failures, and email server users about subscribed views and data-driven alerts. First, however, you need to configure the SMTP server that Tableau Server uses to send email.
In the Tableau Server Configuration utility, click the SMTP Setup tab.
Under SMTP Server:
Enter the name of your SMTP server.
(Optional) If your account requires it, enter a user name and password for your SMTP server account.
If you are not using the default SMTP port 25, change the SMTP port value.
Uncheck Enable TLS so the connection to your mail server is unencrypted. (Encrypted SMTP connections are not supported for alerts or subscriptions.)
For Send email from, enter the email address that will send an alert if there’s a system failure. The email address must have valid syntax (for example, ITalerts@bigco.com or noreply@mycompany), but it does not have to be an actual email account on Tableau Server. (Some SMTP servers may require an actual email account, however.)
For Send email to, enter at least one email address that will receive the alerts. If you enter multiple addresses, separate them with commas.
For Tableau Server URL, enter http:// or https://, followed by the name or IP address of the Tableau server. This value will be used for the footer of subscription emails.
When you start the server it will trigger an email alert. This confirms that you have set up alerts correctly.
