Well, I have an instance running. At startup it outputs federation enabled, host is redacted, but I don't see anything when looking at all. I can't search for other instance communities. I thought I would be able to use my local instance to browse other instance/communities and post there from my instance. Is that not how this works? Did I miss a step setting it up?

Some more details: Any search I do results in a timeout error. This is from the lemmy logs.

In all my years of software development and testing, I've never seen an HTTP status code 101... 101: switching protocols

UPDATE: it's fixed!

Thanks to @[email protected] who pointed me in the right direction, and thank you everyone who contributed to this post in the comments with suggestions and support!

Here are the steps:

add a new network interface

docker network create lemmyexternal

connect the lemmy container (lemmy_lemmy_1, unless you renamed it)

docker network connect NETWORK_ID CONTAINER_ID

(you can get the network and container IDs with docker network ls and docker container ls)

modify the docker-compose.yml to add the new network, and link it to the lemmy service

networks:
  # communication to web and clients
  lemmyexternalproxy:
  lemmyexternal:
  # communication between lemmy services
  lemmyinternal:
    driver: bridge
    internal: true

services:
  lemmy:
    image: dessalines/lemmy:0.17.4-rc.1
    hostname: lemmy
    networks:
      - lemmyinternal
      - lemmyexternal

save, and restart

docker-compose restart

Hi! I decided to experiment with my own instance. Went the docker route, and got everything working, except mail.

I setup postfix, and I can send mail to yahoo from the cli, however neither localhost:25 or actual.fqdm:25 work from the running lemmy_lemmy_1 container. The error is:

• FQDM: email_send_failed: Connection error: Connection refused (os error 111)
• localhost:25 email_send_failed: Connection error: Address not available (os error 99)

Has anyone seen this? Feels like a connectivity issue between the running container and host.

This is not letting me save an email address in my user settings.

I guess the intent is for people to use an external smtp service, rather than set up their own?

UPDATE:

tldr; I got mail working with postfix running locally.

• I tried several "free" smtp relay services, and consistently got timeout errors.
• Out of frustration, I re-enabled my local postfix server and reconfigured Lemmy back to that.
• Tailing the postfix logs, I noticed it was rejecting the connection from the Lemmy instance with a relay not allowed error, which had an "internal IP of 192.x" (from the lemmyinternal network).
• So, I added that IP /32 to "mynetworks" on the host in /etc/postfix/main.cf, restarted postfix, and my instance can now send out emails. Yay!

Thanks for the suggestions everyone. I'll leave this post here in case anyone else runs into this problem.
