Hi Hillel,
The fact is after updating Invoice Ninja, my client didn’t receive any email from us. This has been confirmed when trying to send an invoice to a dummy client.
I had a docker based network setup which has denied internet connection for the docker container “app”.
I could not receive any emails sent via IN. Sending Emails seem to be done directly from the “app” container, so I had to enable internet connection for it. As soon as this has been done, I was able to receive emails.
Hi @Access-InTech
Thanks for your reply and suggestions. My IN is currently installed in a web hosting.
However, finally solved the email issue when sending email from IN by removing MX from Cloudflare. The domain MX dns was mistakenly added into Cloudflare proxy that serves no mail traffic.
