Email delivery problems can often be difficult to troubleshoot, as there are many points along the way where a message could be delayed, rejected, or even silently dropped without the sender ever knowing a problem occurred.
Account owners have access to their message logs to assist in troubleshooting deliver issues. https://support.duocircle.com/solution/articles/5000699696-viewing-your-domain-message-log-files
Your Email server or Client logs should show what error is occurring; if not, you can contact our support team for further help and make sure to include the full headers of any delayed or rejected Emails (including timestamps and Received: entries) where available, and describe the timeframe of the problem to the nearest hour with timezone.
Make sure your Email client, or server, is configured to use the following settings:
Outgoing SMTP Server: outbound.mailhop.org SMTP Port: 25 (default), 2525, or 10025 SMTPS (SSL/TLS): 465 (default) or 10465 Username: Your Username Password: Your Password Authentication Type: Basic (“Auth”, “Login”, “Password”) Use SSL/Encryption: Yes (recommended)
- If you use SPF records, make sure to add “include:outbound.mailhop.org” to your record.
Please make sure you are using your SMTP username, not Email address, and password; the same ones you defined in our system.
