i saw that too, but it sends after. maybe something to do with the domain IP being an ipv6 address? The next line it connects successfully using an ipv4 address. I definitely received an email from this test.
Further info: I did make sure that my user i'm logged in as and sending to are both 'super zabbix admins'
What settings should be populated in 'SMTP: helo' and 'SMTP: email' ?
I assume I don't have to use a real email address (like yahoo, gmail, o365, etc) for the smtp email (since the 'mail' command successfully sends as 'zabbixv3@localdomain' ).
My Settings (with my domain swapped out for 'mydomain.tv')
**[email protected] isn't a real email outside of this config
SMTP Server : localhost
SMTP Server Port: 25
SMTP helo: mydomain.tv
SMTP email: Zabbix-Alerts <[email protected]>
connection Security: None
Authentication: None
