I know externally some of the ways to check email, with external tools like the following-

https://mxtoolbox.com
https://viewdns.info
https://www.mail-tester.com/
https://sendtestemail.com/
https://glockapps.com/
https://senderscore.org/
https://www.sendforensics.com/
https://spamcheck.postmarkapp.com/

What are the best ways to test to see if ns8-mail is receiving and sending emails out. That ns8-mail is working correctly locally with NS8?

Is there a place in ns8-mail to see if emails are sent out and status of them? I know there is Loki (logs).

How would I decipher something sent via ns8-mail in Loki?
How would I decipher something received via ns8-mail in Loki?

Are there other ways to check emails sent out and receiving, that ns8-mail is working, and sending emails out to internet?

Thanks,
Jeff

First of all, look at the Mail > Queue page, to check if messages are left in the queue. You’ll find the delay reason for each message. See Mail — NS8 documentation.

For example, in the Logs page, select the Mail application:

  • Use :postfix/smtp] as search query to see what Postfix is sending out
  • Use :postfix/lmtp] as search query to see message deliveries

The logs should be sufficient, but other tests are possible. For instance, a packet sniffer (like tcpdump) can help, especially for tracking DNS requests, though it is much more complex to use.
