Solved Zabbix - email alerts
-
I just made some changes and told it not to use localhost as the smtp server.

Well THESE are the logs from the SMTP server. Any changes you make it Zabbix won't be record by the SMTP server. But it looks like the settings I gave you worked are you sure the mail was not delivered?

Email is working for me. I'm not seeing your issues.
-
Nothing in the message trace on the office 365 side. I'm adding a gmail address to also get emails to see what happens there.

Switch back to sending through the local host. Let's see what the log tells us. Don't make further changes until the logs are verified.

We got it working. Using localhost and port 25 was correct. The issue, the reason that that was not instantly obvious, is that there is a bug in the Zabbix interface and it shows people and addresses added to a trigger that are not really added. So no alerts were firing and attempting to send emails. We moved it to the localhost, and Mike got the triggers thing figured out and suddenly emails were flooding through.
-
The bug is if the user you are trying to send has the permission level of Zabbix Admin instead of a Zabbix Super Admin they don't really get added to the Zabbix Admins group or something like that. It doesn't make sense. I read this article:
https://www.zabbix.com/forum/showthread.php?p=126105#post126105
and then changed the user account that was supposed to get the emails to a Super Zabbix Admin and the messages started pouring in.

@Mike-Davis that's a huge pain! Why haven't they fixed that already?
-
Might give this a try when I re-build Zabbix in April/May
-
I realize this topic is aging out, but can we get a screen shot of what the localhost config should look like in Zabbix to get it all buttoned up?
I'm stuggling with the same issues, but I don't have info on what to put in all the other fields to make this work using the local postfix server.
I don't want to create a whole seperate email just to set up email alerts if postfix is already running.
Thanks

@cronsloth Do you mean the config page under Administration -> Media Types -> email?

that's the one! Email alerts aren't working for me either, and I found this thread.. Unfortunately haven't been able to get it going yet, nothing shows in the logs /var/log/maillog yet either, so it is probably something easy I am missing.
Happy to start a new thread if needs be

Does the mail command work on its own?
-
yes the mail command by itself works fine and shows up in logs.
[root@zabbixv3 ~]# echo "test message" | mail -s "test email for postfix" [email protected]

Network is unreachable?

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 configSMTP Server : localhost
SMTP Server Port: 25
SMTP helo: mydomain.tv
SMTP email: Zabbix-Alerts <[email protected]>
connection Security: None
Authentication: None -
@cronsloth Your helo could be zabbix.mydomain.tv but otherwise, that's how your config should look. I built a newer zabbix server than the one where I had the issues above. To get the newer one to work, the only thing I had to do was edit my SPF record in DNS ( it's a txt record) to add my Zabbix server as an authorized sender for my domain.

Thanks so much for you quick responses... knowing I got those settings dialed in allowed my brain to stop focusing on them and look elsewhere.
After reading some more documentation... there is an added step that I didn't realize I had to do. I must have missed it before because I was too focused on SMTP settings...
Administration > User Groups > Permissions --- by default 'All Groups' was set to 'None' instead of 'Read-Write' which means any user in that group wasn't allowed to read host data. Why that is a default config idk...
https://www.zabbix.com/documentation/3.2/manual/config/notifications/action/operation/message
Thanks for you help, I changed that setting and boom! Emails came through. #bestforumsEver.
