Hi All,
I am using Joomla on a cPanel server hosted by Heart Internet, so I only have access to cPanel and nothing more. We don't use cPanel for e-mail. When I put our 3rd party mail host SMTP server details in Joomla, and send a test e-mail - it fails. The error is " SMTP connect failed " and " Test mail could not be sent ". I have reported this to Heart Internet however I'm banging my head against a brick wall. They don't appear to know what they are doing, saying it's an issue with my mail host and did I want them to change my DNS records to point to them for e-mail! The mail host I use requires us to whitelist any IPs that will be used to deliver mail, and I had whitelisted my cPanel shared server IP with them. To rule out my mail host, I have also set up an account with mailtrap.io - and I see exactly the same problem with the same errors.
I suspect that Heart likely block all SMTP traffic to external IPs, allowing only their own (which we don't use) but they say not?
I was wondering if anyone here had any ideas as to what might be causing this, so I can point them in the right direction?
