Is it a remote or localhost SMTP server? The error has localhost in it unless if you changed it for your message. I know most ISP's block the SMTP port so you need to use their SMTP server to send out emails. I hope that helps you out.

These are two cpanel servers, one has the main site and email system, the other is a shop and send email back using the IP of the first server, both use the same domain one being a subdomain (shop.) They also don't pass to ISP just between servers, this is where the issue is, I think as the domains are same this could be the issue as I get the error above even though username and password are fine

Check out the below link. Looks like it could be file/directory permissions related: https://forums.cpanel.net/threads/ur...on-data.88525/

It says aythentication failed, that too for localhost. Make sure your script has the smtp server set as mydomain.co.uk or server1's IP and also make sure such a domain or entry does not exist in server2's localdomains. In short, mydomain.co.uk should be present in /etc/remotedomains of server2 and should not be present in /etc/localdomains of server2
