Connect the mail server or Secure Email Gateway (SEG) of your organization to the Zivver SMTP Gateway. Use these specifications:

• Smart host: smtp.zivver.com.
• Port: 587 (preferred) or 25.
• Security: TLS 1.2 (or higher) with STARTTLS.
• Authentication:
  • SMTP credentials:
    • For this, a Zivver admin generates a username and password.
    • When the mail server or SEG requires an email address as a username, extend the generated UUID. Add @smtp.zivver.com.
  • SPF is implemented for outbound messages:
    • Anonymous connection as no credentials are used.
    • smtp.zivver.com checks if SPF passes when a message is submitted.
    • The domain in the From header is checked for if it is allowed to submit messages.
• There must be an active Zivver account for the Sender’s email address (From:).
• The Zivver DNS Settings are implemented so that Zivver can send messages on behalf of the domain(s) that your organization uses to send messages from.
