How does Zabbix Send E-Mail?

[TurboAAA]

I am working on getting zabbix to send e-mail alerts, but for some reason I can not figure out how it works. After playing around with the media settings and googling I figured it would be best to ask someone.

Does Zabbix use it's own internal server, or do I need to configure an external one? We have mail servers that can be used, but it would be nice if it had it's own internal system.

Same question

Hello,

I have also dig alot but unable to send alerts on my email. Please any zabbix specialist help !.

Thanks!

Please check your media setting.

Administration -> Media types and click Email.

Does your mail server has been set at 'SMTP server'?

Konnichiwa Atsuhi San,

I have attached the screenshot.

Before I have put my own mail server details as well but not working.

If you want can I send you zabbix credentials, so you can check all the stuff from your side as well?

Thanks in advance.

Regards,
Rahul

You do not have something output to the mail server log?
Rather than localhost in some environments, it might need to be specified as localhost.localdomain.

[rahulchandyok]

Yes, I don't have any output in my mail logs. I have changed localhost to localhost.localdomain but no luck.

One more thing I have changed my passwd file but In my monitoring it's not showing some warning in last 20 issues.

Any idea?

In my understanding so far in zabbix we added our server, we can setup triggers we will get notify for particular service if something went wrong.

media type: Setup for alert, from whom we will get notify.

User section: We can setup email id to send zabbix alert.

Action: We can setup condition and operation

Please rectify me if I 'm wrong?

Can you please take a look once?

Thanks!

Please check user permission.

Do specified user that set 'send to' have access permissions to failur host?

Administration -> Users and click user name.
Next, select Permissions tab.

That host has been listed on Read-write or Read only window?

Later I have get changed passwd file info in zabbix.

Attached screenshots of all.

I know it's pretty straight forward, but have you tried relaying off of local host from the command line

Zabbix does require that the relay be setup, so if your just pointing it to your localhost without it being configured to relay I don't think it will work.

[rahulchandyok]

Now I have received the email on my GMAIL. but I don't know how it's worked hahahaha

I will work more and let you know if 'm stuck again.

If you can receive the e-mail in your gmail, the mails themselves are likely being sent.

I would look towards the filtering/junk mail on your destination server, it's likely that it's being blocked somewhere. It's pretty common for people to block mail that would look like the zabbix e-mails as they don't have a valid domain/reply/lookup/etc..

[TurboAAA]

Sorry it took me so long to come back to my own post, there were other emergencies to deal with.

My problem is that I do not understand how the email process works in Zabbix. I know to use Administration -> Media types -> Email but I have no understanding of what these fields need. I also do not know how Zabbix sends email without credentials to the SMTP server.

For example,
SMTP server : <or corporate email server>
SMTP helo : <corporate domain>
SMTP email : zabbix.localhost

What does Zabbix do with this information?

[coreychristian]

Honestly I couldn't get into the specifics as I am not 100% familiar with them. Most SMTP Servers we use at my company don't require authentication to send outbound e-mail.

I think you are fine doing it the way you are, you just need to talk to your messaging admins and find out what is blocking the e-mail you are sending, or if they have any requirements you must meet sending mail in from your server.

It may be just as simple as changing the SMTP E-mail to '[email protected]'.

As I mentioned though the outbound appears to be working for you since it will go through to your g-mail, so there must be some filtering going on somewhere.

Actually I am the OP, you have been helping another user that joined my thread. Sadly reading over the previous posts didn't help my lack of understanding.

Let me try asking in a different way. I want zabbix to send an email to our helpdesk ticketing system. How can I tell zabbix to send an email to [email protected]?

Sorry about that, terrible about reading the posters name sometimes.

Essentially most of it is in this thread.

So for zabbix you need a smtp relay server that doesn't require authentication. After that you need to setup the following (sorry guessing most of this you already completed)

1. Create the media type
2. Create a User that has read only access to the systems you want to send an e-mail for.
a. Also setup the media for that user with the helpdesk e-mail address.
3. Create an action (Event Source Triggers), that will send a notification to that user when the particular triggers fire.
