Solved Zabbix - email alerts
-
@Mike-Davis I think I gave up trying to get the mail.protection thingy to work and ended up just using a mail box with port 587 and STARTTLS

So install ssmpt and mailx and go about it that way? I could try that with a gmail account and see if I get anything that way.

Are you sure that that is needed? Does it even use Postfix? Have you tested it without that?

mailx is a client app, not used for applications to send mail. That's just for you to send them by hand.
Do you have reason to believe that postfix doesn't have TLS capability by default? This is an enterprise OS here. Our matching system didn't need anything special to handle TLS to O365, right?
-
Postfix can most certainly use TLS.

Do the logs tell you anything?
I looked at the /var/log/zabbix/zabbix_server.log and didn't see anything related to email. What are the names of the other log files I should look at?

Well normally /var/log/maillog, but it is completely empty prompting me to think that postfix is not being asked to send anything.

right, that's why I set up the connector in o365. So I could send mail in on port 25 without authentication.

Then it is not using

Not sure it's needed. I was looking at this guide:

I'm confused. Doesn't that mean the opposite of what I said?

Not sure it's needed. I was looking at this guide:
http://www.tecmint.com/configure-zabbix-to-send-email-alerts-to-gmail/Why? It's purpose is expressly to do something different from what we have today: "This tutorial will briefly discuss you on how to setup Zabbix server to send mail reports to a Gmail address by using SSMTP program, without the need to install and configure any local MTA daemon, such as Postfix, Exim etc."
We already have Postfix installed, running and you said that you tested it and it worked.

Let's stick to testing one thing at a time. Don't hit one hiccup and start ripping and replacing the entire email system. Chances are we are dealing with something really simple, like Zabbix isn't trying to send email or isn't trying to use the MTA. If we have to put SMTP details into Zabbix, it seems like it is trying to send directly without Postfix, otherwise it would use the Postfix settings, right?

@scottalanmiller
This command works:sendmail <myemailaddress>@ntg.co < /tmp/email.txtThat was to make sure that no firewalls or anything were getting in the way. That said, when I checked the headers, it didn't seem to connect directly to the o365 connector where I expected it to.

I agree.

Where did you expect it to? Should be TLS on Port 25.

Before we head down any rabbit holes, change the settings in Zabbix to send to port 25 on the local machine.
