I've been working through the installation and configuration of Zabbix over the past couple of days and I think I've finally got everything working... except the sending of notifications / alerts.

I'm running on a Ubuntu server which is using Exim to send emails. I'd previously used this Exim setup to send notifications for Nagios so I know that Exim itself works.

However, I can't seem to get Zabbix to send out notifications.

Here's what I've done so far:

• Set up a "test trigger" like so:

Trigger severity >= "Information" Send message to User "Admin"

• The Admin user has a email contact (and I've sent command line emails from Exim on the server using "sendmail" to this email address successfully)
• The media type for email is set. (I've tried 127.0.0.1)
• I've checked the user permissions and it is read/write for all host groups

The triggers are definitely getting set but no actions are being called... I think my problem is within Zabbix as it's not actually executing the actions

And idea how to configure this correctly?
