Doesn't look like it, please enable SMTP debug logging and use the send a test email button in Admin > Email Settings, and send us the full output.

One thing I would check is the attachment size limit on your mail server, there is a chance some of the reports exceed your mail server's attachment size limit and could fail. All of them failing wouldn't likely be that so we'll need to get the debug output to see what's occurring now but I'm wondering if those individual ones failing before if that's what occurred. You would need to check the mail server's logs for additional info, have your mail admins run a trace on one of the reports and see what the mail server logs show.

Taken from the link above:

Note: PHP Mailer requires PHP 5.6 or higher to use a TLS 1.2 connection.

You can also try changing the port from 25 to 587 in the XI settings and see if that helps, I had a customer that did that and it resolved it for them as well.

I have been slowly looking at upgrading PHP. We have tried to update to PHP 7 but a Nagios Dependency is hindering me from doing the update. We have enabled the php70 repo so a yum update will attempt the update.

Any suggestions?

You're skipping the very first steps of the guide directly related to the nagiosxi-deps package it's complaining about:

https://support.nagios.com/kb/article/n ... 7-860.html

But before you do that, send the output of this command:

Yep didn't see the "must be on php 5.5" part. Thanks

[root@nagios ~]# rpm -qa | grep nagiosxi
nagiosxi-deps-el7-5.7.5-1.noarch
[root@nagios ~]#

You need to do these:
Then follow the rest of the directions from the guide.

Hi,

Since PHPmailer is being used to send the reports then it definitely could be PHP related.

Were you able to perform the PHP upgrade?

Thanks
