Zabbix 3.2.3 on CentOS 3.10.0-514.6.1.el7.x86_64
We normally say "CentOS 7". CentOS is the OS family name. 3.10.0 is the Linux kernel version. We can deduce the OS from that, but it's not how it is said. This is what got Art the other day with the Debian 2 thing.
-
The command to get your operating system version is...
cat /etc/redhat-releaseThe uname command that you used is for the kernel identifier.
-
Do the logs tell you anything? Might easily be trying to use a PHP SMTP component that is not there or is not working.

I read your post the other day and thought I need to be specific on the version. Which switch on the uname command tells us that it's CentOS?
I tried all the variations I could think of and couldn't get anything to spit out CentOS/RedHat/or something that I recognized. That's why I just pasted the output from uname -a.

None, uname queries the kernel, not the OS.

What's the command if you don't know that you're on RedHat or something else?
-
Here you go...
[root@zabbix ~]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) -
Just for reference, the system is running postfix, not sendmail.
-
What settings are you using for SMTP and Office365?

@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.

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.
