SMTP configuration for the Serv-U File Server

Configure an SMTP connection to send email for events which are configured to use email actions.

You can configure SMTP on the server or domain level, or both. SMTP configuration at the domain level can be inherited from the server level.

The SMTP configuration dialog is located on the Events tab on the Server Details and Domain Details pages, and also in the Domain Wizard.

  1. Click Configure SMTP to launch the dialog.
  2. Enter the SMTP server and port.
  3. Check the checkbox to use SSL. This will also reveal additional checkboxes if you want to use a SSL Certificate and/or Explicit SSL.
  4. Enter the email address and name you want to assign to the emails generated.
  5. If your server requires authentication check the checkbox and supply the account name and password.

Test the SMTP configuration

  1. Click Send Test Email.
  2. In the Send Test Email window, specify the email address where you want to send the test email to, and click Send. Optionally, you can edit the subject and content of the test message.
  3. If the email was sent successfully, click OK on the confirmation window to save your SMTP configuration, or click No to return to the SMTP Configuration window.

    If an error occurs at any stage of the configuration test, Serv-U File Server returns one of the following error messages in the SMTP error window:
