Zabbix Mail sending issue

[vnoc]

Hi All,

I am facing an issue while sending the mails

I am using zabbix_server (Zabbix) 4.0.0alpha5 version


In the UI it is showing mail sent but i am not receiving email to my mail box. In the Audit logs & Action logs also there is no error.


There is no permission issue as well as i am using zabbix administrator host group and i am uing default admin to send the mail which doesn't require any permission.


Please help me in fixing this

Hi, vnoc!

Please try to increase log level for process "alerter":
zabbix_server -R log_level_increase=alerter
No need to restart anything! Repeat the steps and check zabbix_server.log for any errors. If the debug was successful you can decrease the level with
zabbix_server -R log_level_decrease=alerter

Regards,
Aigars

Sorry, vnoc. You screenshot is not very readable

Just tested more accurate workflow to debug this issue. At first set DebugLevel=0 in zabbix_server.conf. Then:

#stop zabbix server
systemctl stop zabbix-server
#empty existing log
> /var/log/zabbix/zabbix_server.log
#start zabbix server
systemctl start zabbix-server
#increase only zabbix alerter from level 0 to 4 by runing this command 4 times:
zabbix_server -R log_level_increase=alerter

#when you output log
cat /var/log/zabbix/zabbix_server.log
#it should say only

I have not tested 4.0 yet, but a simple test to see if the issue is with Z or your email system is to try having Z send the email notifications to a different account like gmail or something like that. If the action log shows that Z send the message, I suspect the issue falls outside of Z.

If in the Action log you see green - Sent, then I would check for a problem on a mail server or try some other SMPT.
If there is nothing in the Action log, then check does recipient user have permissions affected Host group.
