What to do when Gmail marks all the mails from your server as spam

What to do when Gmail marks all the mails from your server as spam

If you're self-hosting your services and having trouble getting your emails through Gmail and infuriated by Google's non-existent support, you're not the only one. I'd like to share my experiences trying to get it sorted out.

I'm the author of the post above. You can tell how arrogant Google employees are from all the previous posts he made in the past.

Sample Docker-compose file which shows how to set up Sonarr, Radarr, Prowlarr, Lidarr, QBittorrent and a VPN container so that all all traffic from the containers is routed through the VPN. Also includes Plex and get_iplayer containers, which are not routed through the VPN.
# Docker compose to set up containers for all services you need:
# VPN
# Sonarr, Radarr, Lidarr, Qbittorrent
# Non-VPN
# Plex, get_iplayer
# Before running docker-compose, you should pre-create all of the following folders.
# Folders for Docker State:
# /volume1/dockerdata. - root where this docker-compose.yml should live
# /volume1/dockerdata/plex - Plex config and DB
# /volume1/dockerdata/sonarr - Sonarr config and DB

Walkthrough of what I did to increase performance on my Synology NAS box during an expansion, and afterwards.

Performance on Synology RAIDs

(especially while expanding)

Warning: The exact commands may not match for your particular linux OS / Synology(NAS) device. I had to customize the commands after exploring my particular system's setup.

If you're new to linux, or this is a new piece of hardware / a new synology device, jump down to the section called "Inspecting a setup"
