Outgoing server (SMTP) xx.com.au failed

Hi, I know this thing has many posts, I have spent all of today trying to work it out, all to no avail.  So apologies upfront for the self-managing WHM and Cpanel install on my first G Cloud hosting project.
I am running through Cloudflare and tried all the testing but, frustratingly, I still get an error.
First up, failed email header:

Next up, WHM Zones:

Next, Cpanel Zone Records:

And Finally, Cloudflare DNS:

My head is spinning, so I hope what I have included reveals a simple answer I am missing.

Thanks in advanced

  The body of the bounceback email should give an idea of why it was unable to be delivered - such as:

  The response from the remote server was:550 No such person at this address"

  or

  DNS Error: DNS type 'mx' lookup of domain.invalid responded with code NXDOMAIN Domain name not found: domain.invalid 

  What is the bounceback message you get?

  Hi there,

  First of all, are the MX records for the domain cjps.com.au correct? We suggest to get the MX records from your mail service provider and update it in Cloudflare. Also, check SPF is correct and update it in Cloudflare. If you are using Google mail service, they provide different MX records and TXT records (SPF, DKIM, DMARC). Get in touch with your mail service provider to confirm the records.

  Secondly, we advice to check the mail logs for the domain or the email account. You can grep your email account to specifically investigate the mail logs. 
  Command to use: cat /var/log/exim_mainlog | grep email_address

  You can also check the ID generated to go through in-depth investigation. 
  Command: exim -Mvh 1rQKTE-005ihQ-OM 
  Through the above command it will show the header and other few things to know more about the issue.

  You can also check in the Track delivery in cPanel https://docs.cpanel.net/cpanel/email/track-delivery/
  The same option is available in WHM as "Mail Deliver Reports".

  
  We also suggest to check your routing in cPanel under "Email Routing"

   

  Regards,
  MilesWeb!

  Thanks MilesWeb and MilesWeb,

  I think I am out of my depth here... I am using the 'default' mail service within WHM/Cpanel, I go to webmail (RoundCube) and it receives, but not sends. 
  I might just get a third party to host emails, it might be easier.

  Hi Simon,

  We suggest to check the logs in the mail logs. Mail logs will help you identify the exact issue with the mail functionality. You can ask your hosting provider for help but it seems you have opted for a self-managed server. If you are unable to locate and read the Exim logs, we advise you to get technical help or switch to a mail service provider who can provide you with all technical support if you ever cross any issues with the email.
