* fix: Workaround `postconf` write settle logic
After updating `main.cf`, to avoid an enforced delay from reading the config by postfix tools, we can ensure the modified time is at least 2 seconds in the past as a workaround. This should be ok with our usage AFAIK.
Shaves off 2+ seconds roughly off each container startup, reduces roughly 2+ minutes off tests.
* chore: Only modify `mtime` if less than 2 seconds ago
- Slight improvement by avoiding unnecessary writes with a conditional check on the util method.
- Can more comfortably call this during `postfix reload` in the change detection cycle now.
- Identified other tests that'd benefit from this, created a helper method to call instead of copy/paste.
- The `setup email restrict` command also did a modification and reload. Added util method here too.
* tests(fix): `mail_smtponly.bats` should wait for Postfix
- `postfix reload` fails if the service is not ready yet.
- `service postfix reload` and `/etc/init.d/postfix reload` presumably wait until it is ready? (as these work regardless)
* chore: Review feedback - Move reload method into utilities
* chore(`aliases.sh`): Filepath to local var `DATABASE_VIRTUAL`
* chore(`accounts.sh`): Filepath to local var `DATABASE_ACCOUNTS`
* chore(`accounts.sh`): Filepath to local var `DATABASE_VIRTUAL`
* chore(`accounts.sh`): Filepath to local var `DATABASE_DOVECOT_MASTERS`
* chore(`bin/open-dkim`): Filepaths to local vars (accounts,virtual,vhost)
* chore(`relay.sh`): Filepath to local var `DATABASE_SASL_PASSWD`
* chore: Rename method
Prior PR feedback suggested a better helper method name.
* chore: Normalize filtering config lines as input for iterating
* chore: Remove `_is_comment` helper method
No longer serving a purpose with more appropriate filter method for pre-processing the entire config file.
* fix(listmailuser): Don't parse comments
Avoids passing comments to `dovecot_quota_to_hr()` which fails to handle it and would throws errors.
* chore: Move config filter method to `helpers/utils.sh`
This PR does two small things:
1. The log level, in case it is unset, will now be "calculated" from
`/etc/dms-settings` and not always default to `info`. This way, we
can ensure that more often than not, the log level the user chose
when starting DMS is used everywhere.
2. I noticed that the way I obtained the log level could be used to
obtain any env variable's log level. I therefore added a function to
`utils.sh` in case we use it in the future.
