Well, I figured out with graylog. Do I need to upgrade to version 6 or will graylog 3 work on version 5? If not, where can I see how to update the version of elasticsearch, despite the fact that it works and stores 1.5 billion logs?

Do a snapshot or a backup of your VM and try to do it step by step with the docs @jan already posted…
Even I did it successfully 😃

From the page with the upgrade information:
> Graylog 2.5 is the first Graylog version that supports Elasticsearch 6, the upgrade is recommended as soon as possible but might need more attention and include the need to reindex your data.
From the System Requirements page:
- [Elasticsearch 5 or later](https://www.elastic.co/downloads/elasticsearch)

I think this is because of nginx. I have a redirect from port 9000 to port 80 and ssl connection using nginx

without knowing what you have configured nobody is able to help you - because google is your friend about http returncodes and their meaning …

configure your Mailserver that Graylog is able to send messages as this sender. Just read the error message complete.
