Zabbix not sending notification emails

[kbrede]

I'm running zabbix-2.0.6-1.el6.x86_64, installed from the yum repository. I'm not able to get Zabbix to send email alerts.

Setting up the test.

1. Created host

2. Created user:

User is in the "Zabbix Administration" group.

My email address was added under the "media" tab.
When active: 1-7,00:00-24:00
Use of Severity: all checked

User type: Zabbix Super Admin
All host groups and hosts set to read/write.

3. Created an item: "Simple Check" icmpping[137.48.1.127,2]

4. Created a trigger: {server.example.com:icmpping[137.48.1.127,2].max(30)}<1

5. Set up email media device. From the Zabbix server email is routed through a local relay server.

SMTP Server: mailrelay.example.com
SMTP helo: example.com
SMTP email: [email protected]

6. Created "Mail Send" action.

Default Subject: {TRIGGER.STATUS} and {TRIGGER.NAME}
Default Message:

Trigger: {TRIGGER.NAME}
Trigger Status: {TRIGGER.STATUS}
Trigger Severity: {TRIGGER.SEVERITY}
Trigger URL: {TRIGGER.URL}

Left "Conditions" blank.

Under "Operations" added my user. Operation type "Send Message." Send only to email. Default message checked.

-------------------------------------------------------------------------------

I can "echo test | mail -s test [email protected]" and email goes out fine from the Zabbix server.

When I shut off the interface for server.example.com the Zabbix monitor shows down but I see no evidence in /var/log/maillog on the Zabbix server or on the mailrelay that any message is sent from the Zabbix monitoring service.

For the media type I've also tried:

SMTP Server: localhost
SMTP helo: localhost
SMTP email: [email protected]

What am I doing wrong?

Thanks,
Kent
