During cold start, var directory may not exist and we try to chown
the var directory which fails if it doesn't exist. We want to make
and chown the var directory in that case otherwise, mailman will not
be able to write to path `/opt/mailman` to create it's own var
directory.
* add smtp user, password from environment
add smtp user, password from environment to mailman.cfg
* Update README.md
document SMTP authentication via docker-compose.yml
* Update README.md
* Create docker-compose-traefik.yml
real life example
* remove examples folder for later use
Replace them with:
* containers' hostnames
* gateway's IP address for default SMTP_HOST
* Core: when SMTP_HOST undef, echo the default value
* docker-compose: add port mapping
* docker-compose: drop network driver conf
* Exim macro: use localhost as LMTP host
* Update README.md
* docker-compose: Limit port mapping to loopback
* Update other docker-compose example files
We have to append ">>" to /etc/mailman.cfg and not to overwrite previously written content with ">".
Problem was that the database config made in setup_database was overriden.
* Add code for auto-detecting database class for common cases.
* Fix unintentional space indentation instead of proper tab indentation
* Fix another left-over spaces indentation (sorry)
Even though the 'master.lck' is supposed to prevent race conditions, it needs to
be manually removed if the container did not shutdown gracefully. Remove the
manual check for the lock file and force mailman to remove it.
Also, set the stop_grace_period to 30s, which would allow Core to stop
gracefully and not leave the lock file over. Default value in case of Docker is 10s.
