On the test I will use Zabbix 3.0.3 and iRedMail 0.9.4 installed in Ubuntu Server 14.04.4 LTS.
First, in the Zabbix panel, activate the action by opening the tab “Configuration” – “Actions” and activate “Report problems to Zabbix administrators“. In it I also, to see the names of the hosts, changed both topics of the letter with:
{TRIGGER.STATUS}: {TRIGGER.NAME}
on
{TRIGGER.STATUS}: {HOST.NAME1} {TRIGGER.NAME}
In Zabbix, the email notification method was initially added, but depending on the settings of the mail server it can work or not work. You can find it by going to Zabbix under the administrator and opening the tab “Administration” – “Media types” – “Email“.
When configuring with iRedMail, I specified the following parameters:
Name: Email
Type: Email
SMTP server: mail.example.com
SMTP server port: 25
SMTP helo: example.com
SMTP email: user@example.com
Connection security: STARTTLS
Checkboxes for “SSL verify peer” and “SSL verify host” did not put
Authentication: Username and password
Username: user@example.com
Password: PASSWORD
check for “Enabled”
If the mail server is in the same system as the Zabbix server, you can try to configure both the above, but where “Connection security” and “Authentication” select “None”.
Also in the user profile, in the tab “Media” need to add:
Type: Email
Send to: mail for notifications
When active: time when it is allowed to be alerted
Use if severity: what importance of notification to send
check for “Enabled”
Done.
