Consistency pass, formatting cleanup and fixes, introduce admonitions, add front-matter. --- docs: Add front-matter --- docs: Fix and format links - Some links were invalid (eg files moved or renamed) - Some were valid but had invalid section headers (content removed or migrated) - Some use `http://` instead of `https://` when the website supports a secure connection. - Some already used the `[name][reference]` convention but often with a number that wasn't as useful for maintenance. - All referenced docs needed URLs replaced. Opted for the `[name][reference]` approach to group them all clearly at the bottom of the doc, especially with the relative URLs and in some cases many duplicate entries. - All `tomav` references from the original repo prior to switch to an organization have been corrected. - Minor cosmetic changes to the `name` part of the URL, such as for referencing issues to be consistent. - Some small changes to text body, usually due to duplicate URL reference that was unnecessary (open relay, youtous) - Switched other links to use the `[name][reference]` format when there was a large group of URLs such as wikipedia or kubernetes. Github repos that reference projects related to `docker-mailserver` also got placed here so they're noticed better by maintainers. This also helped quite a bit with `mermaid` external links that are very long. - There was a Github Wiki supported syntax in use `[[name | link]]` for `fetchmail` page that isn't compatible by default with MkDocs (needs a plugin), converted to `[name][reference]` instead since it's a relative link. --- docs: Update commit link for LDAP override script Logic moved to another file, keeping the permalink commit reference so it's unaffected by any changes in the file referenced in future. --- docs: Heading corrections Consistency pass. Helps with the Table of Contents (top-right UI) aka Document Outline. docs: codefence cleanup --- docs: misc cleanup --- docs: Add Admonitions Switches `<details>` usage for collapsible admonitions (`???`) while other text content is switched to the visually more distinct admoniton (`!!!` or `???+`) style. This does affect editor syntax highlighting a bit and markdown linting as it's custom non-standard markdown syntax.

| Override the Default Configs | Postfix |
The Postfix default configuration can easily be extended by providing a config/postfix-main.cf in postfix format.
This can also be used to add configuration that is not in our default configuration.
For example, one common use of this file is for increasing the default maximum message size:
# increase maximum message size
message_size_limit = 52428800
That specific example is now supported and can be handled by setting POSTFIX_MESSAGE_SIZE_LIMIT.
Postfix documentation remains the best place to find configuration options.
Each line in the provided file will be loaded into postfix.
In the same way it is possible to add a custom config/postfix-master.cf file that will override the standard master.cf. Each line in the file will be passed to postconf -P. The expected format is <service_name>/<type>/<parameter>, for example:
submission/inet/smtpd_reject_unlisted_recipient=no
Run postconf -P in the container without arguments to see the active master options.
!!! note There should be no space between the parameter and the value.
Have a look at the code for more information.
