Test your entire SMTP delivery network by delivering to any unique IP Addresses found in DNS. In addition, selecting the Connect option will run a quick telnet session in order to solicit the response time; selecting the A Record option will attempt to deliver to the A Record for the domain to see if it can bypass any filtering service running on each server.
To test your SMTP delivery network, perform the following:
- Enter the domain into the field provided, select the Connect and/or A Record option as required, and click the Check Network button.
- The test results will be shown. Depending upon options selected, the results may show MX Record response times and whether or not the domain has an A Record.
