Tools ‒ SMTP Network Delivery Test

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:

1. Enter the domain into the field provided, select the Connect and/or A Record option as required, and click the Check Network button.

2. The test results will be shown. Depending upon the options selected, the results may show MS Record response times and whether or not the domain has an A Record.
