I tried both TLS/SSL SSL/TLS server configs none of them worked, yet each had another set of errors, right now when I am going on Nginx proxy to test the mail, I get a Gateway timeout, now I am not sure why is that. Since Uswgi supports SSL itself why does one needs Nginx as a proxy? We know the role of a proxy, the only issue I see here is that on current documentation and current steps followed with Docker, we never made possible even a testing mail to work.
We tried default cpanel/WHM email accounts, they are according to RFC standards, and I also tried Zimbra mail server client, tried configs that work flawlessly on other Django setups I have, such as Taiga.io. Same it works same mail servers work accross all our services, from ruby, to python applications.
Any help is welcomed, if someone makes a living with Sentry, PM me maybe we can agree on some help to have this instance running properly. At this point all works, beside mail.
One type of error:
SMTPServerDisconnected: Connection unexpectedly closed: timed out
Second type of errors:
error: [Errno 113] No route to host
