I think you need to get your partnership updated with NewRelic so you offer free standard plans instead of lite: https://discuss.newrelic.com/t/faq-how-is-the-partnership-standard-account-different-from-the-lite-account/3152

This is important as Standard brings great features:
- allows monitoring of wordpress plugins and themes.
- web transaction summary so you can tune effectively
- Database analysis of poorest performing calls
- 1 week of data in a single view
- Embeddable charts

There is an option that says "upgrade to standard" in New Relic app monitoring under Wordpress and Database. But the page forwards to the CouldWays upgrade to Pro page. So this is in your hands to fix.

I have a separate Standard Plan and at least for now I want to be able to use that instead of the lite.
Or better just upgrade the lite to standard for everyone.

This is what my other Standard subscription looks like. Web Standard vs Web lite is the difference.

I use the rackspace addon and have 7 maiboxes, covering 3 domains.

Because the email is with rackspace I have set my Mx records to use their servers, however there is no option for auto responders, catchall or most importantly email forwarding.

Im able to forward from a mailbox to another account, but I cannot just have a simple forward. This is very restrictive because it means for each email address I want to use I have to buy another mailbox, even if no mail ever sits in the box.

As an example I have
staff1@mysite.com
staff2@mysite.com
staff3@mysite.com
all of which have mailboxes, hosted with you.

But we have a number of different emails which I want to direct to one staff member or another and I dont want to have to pay for each forward to be a mailbox that will not be used.

So I want to be able to send
jobs@mysite.com - staff 1 mailbox
commercial@mysite.com - staff 1 mailbox
contact@mysite.com - staff 2 mailbox

Also I cant even forward to non mysite.com emails so set up
blogs@mystie.com -> me@gmail.com

Autoresponders is also a problem. Buying just a single mailbox with rackspace ties my entire email system to them, so we need more direct flexibility in how to handle emails.

I just found out an error.

I create a Vultr server. I explored all the addons and forgot to disable the SMTP addon when I enabled it. I had no intention to use it just to see what addons Cloudways have. Later that week when I was installing new wordpress I found out that my postfix email doesnt work anymore. After I figured it out with your cloudways support I disabled it. However the email still didn't work. I have tried to reset a dummy username to get a new password to check and also create a new username to get a notification of the new username and password.
So what I was suggested to create a new server and try to see if this happens again when SMTP addon is disabled.
So my understanding that if you don't want to use the SMTP you can disabled it and Cloudways infrastructure should re-configure the server so postfix should work as normal but in this case it doesn't.
