Hey guys. I am having issues with my e-mails which I have not been able to trace. All the config is standard as it comes with the KH cPanel set up. After a week, perhaps two or even a month you are unable to download or send e-mails. Thunderbird returns "connection refused" which means to me it could contact the server but it was rejected. Normally it would say "timeout" or something if (for example) it was on the wrong port. It works fine otherwise, but randomly just stops. The service is still running but I can't download / send e-mails. I have tried restarting the service via WHM but this doesn't resolve it. I have to reboot the VPS to make it work again. Anyone have any suggestions or ideas? Thanks!
