Best ways to test to see if ns8-mail is receiving and sending emails out

[davidep (Davide Principi)]

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.

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

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

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

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.
