Adjust envrionment variables - more sensible defaults (#2428)
The new setup will now set env variables on one place and on one place only. The old setup used two separate places wich is not DRY and confusing. Some default values changed: 1. PFLOGSUMM_TRIGGER: logrotate => none 2. REPORT_SENDER: mailserver-report@HOSTNAME => mailserver-report@DOMAIN 3. REPORT_RECIPIENT: "0" => POSTMASTER_ADDRESS One env variable was renamed: REPORT_INTERVAL => LOGROTATE_INTERVAL I believe these defaults to be more sensible, especially the REPORT_RECIPIENT address. The PFLOGSUMM_TRIGGER value was changed to `none` because otherwise people would start getting daily Postfix log summary reports automatically. Now, this is opt-in, and reports are sent only when enabled properly. Some of the variables changed were marked as deprecated. I removed the note, as the variables now bear some (sane) defaults again for other variables (i.e.) REPORT_RECIPIENT is now default for other recipient addresses.

Changes the interval in which logs are rotated and a report is being sent (deprecated).
|
||||
|
||||
- **daily** => Send a daily report
|
||||
- weekly => Send a report every week
|
||||
- monthly => Send a report every month
|
||||

Note: This variable used to control logrotate inside the container and sent the pflogsumm report when the logs were rotated.
|
||||
It is still supported for backwards compatibility, but the new option LOGROTATE_INTERVAL has been added that only rotates
|
||||
the logs.

##### LOGROTATE_INTERVAL
|

Defines the interval in which the mail log is being rotated.

Changes the interval in which a report is being sent.
|
||||
|
||||
- **daily** => Rotate daily.
|
||||
- weekly => Rotate weekly.
|
||||
- **weekly** => Rotate weekly.
|
||||
- daily => Rotate daily.
|
||||
- monthly => Rotate monthly.
|
||||
|
||||
Note that only the log inside the container is affected.
|
||||
The full log output is still available via `docker logs mailserver` (_or your respective container name_).
|
||||
If you want to control logrotation for the docker generated logfile, see: [Docker Logging Drivers](https://docs.docker.com/config/containers/logging/configure/).
|
||||
!!! note
|
||||
|
||||
Also note that by default the logs are lost when the container is recycled. To keep the logs, mount a volume.
|
||||
`LOGROTATE_INTERVAL` only manages `logrotate` within the container for services we manage internally.
|
||||
|
||||
The entire log output for the container is still available via `docker logs mailserver` (or your respective container name). If you want to configure external log rotation for that container output as well, : [Docker Logging Drivers](https://docs.docker.com/config/containers/logging/configure/).
|
||||
|
||||
By default, the logs are lost when the container is destroyed (eg: re-creating via `docker-compose down && docker-compose up -d`). To keep the logs, mount a volume (to `/var/log/mail/`).
|
||||
|
||||
Finally the logrotate interval **may** affect the period for generated reports. That is the case when the reports are triggered by log rotation.
|
||||
!!! note
|
||||
|
||||
This variable can also determine the interval for Postfix's log summary reports, see [`PFLOGSUMM_TRIGGER`](#pflogsumm_trigger).
