Some e-mail servers do not respond to pings on purpose. It keeps hackers from discovering them easily. But if you typed in ping and the mail.authsmtp.com and it showed it was attempting 62.13.128.188 then this is the correct IP address for the mail.authsmtp.com.
When you open SMTP Viewer you must enable it to work.
- When you start SMTP Viewer it should say in the title bar "Monitoring UDP port: 29298 (0x7272)"
- From the menu click Device --> Select Device (you'll need to be on the network with your H2-ECOM100.
- Choose your ECOM100 from the list and press <OK>.
- In the small top text window, type in emailtrace and press <Enter> key.
- It should give a date/time in the big window and say "EMail Trace On". If it says "Off" then just do the emailtrace again (this toggles).
- Next, leave this running and start NetEdit3 and right-click on your H2-ECOM100 and try the Test Email again.
Let us know.
Also, does your email relay have a login and password?
