Connect to the Zivver SMTP Gateway
Connect to the Zivver SMTP Gateway
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:
- A Zivver admin generates a username and password for this.
- If the mail server or SEG requires an email address as a username, extend the generated UUID by adding
@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 to see if it is allowed to submit messages.
- SMTP credentials:
- 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.
