Run Mail2Most as a service

You can run Mail2Most using docker, docker-compose or as a systemd service.

Using docker you need to change the path to your mail2most.conf

docker run \
  -v /path/to/mail2most.conf:/mail2most/conf/mail2most.conf \
  virtomize/mail2most:latest

e.g. if you are in this repo:

docker run \
  -v $(pwd)/conf/mail2most.conf:/mail2most/conf/mail2most.conf \
  virtomize/mail2most:latest

The latest tag image is rebuild on a daily base to get newest OS package updates inside the docker image.

Using docker-compose you can just edit the conf/mail2most.conf or change the path inside the docker-compose.yml to your config:

    volumes:
      - ./conf/mail2most.conf:/mail2most/conf/mail2most.conf

    volumes:
      - /path/to/my/mail2most.conf:/mail2most/conf/mail2most.conf

then just start a container user

Common problems

Problem: mail2most crashes after profile changes

Solution: This happens when the data.json is not consistent to the config changes. Delete data.json to solve this problem.

Problem: Channel contains special characters mattermost can not found the channel

Solution: Mattermost does not support special characters for channel names, only in display names. To find the correct channel name use the last part of the url found under view info
