Use Cases

1. Improved Deliverability

This service enhances deliverability, especially for users who may face IP blacklisting issues with Google or Microsoft. By routing emails through our gateway, you can bypass blacklisting problems and improve inbox placement without the need for SPF records.

Note for Office 365 Users: If using a connector, complete the validation process even if it initially fails, as Office 365 will prompt you to confirm and finalize the setup.

2. Integration with Third-Party Services

For users needing to route emails through third-party services (such as encryption services like Zix or archiving solutions), No Password Smart Hosting provides flexible routing options. Our support team can configure routing rules to direct specific departments (e.g., accounting) through the third-party gateway while allowing other emails to bypass it.

Example: Configuring Routing Rules


$listOfAddresses = [
  "user1@sendercom",
  "user2@sendercom",
  "user3@sendercom",
];

if ($username == "customer" && in_array($sender, $listOfAddresses)) {
  SetDestination("the.smart.host", 25);
}

This script routes specified addresses to the defined smarthost, leaving others unaffected.

Conclusion

No Password Smart Hosting simplifies the configuration process by handling authentication on the backend. With this service, Google Workspace and Office 365 users can securely route messages via outbound SMTP, improve deliverability, and integrate third-party services with ease.
