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.

| User Management | Aliases |
Please read the Postfix documentation on virtual aliases first.
You can use setup.sh instead of creating and editing files manually. Aliases are managed in /tmp/docker-mailserver/postfix-virtual.cf. An alias is a full email address that will either be:
- delivered to an existing account registered in
/tmp/docker-mailserver/postfix-accounts.cf - redirected to one or more other email addresses
Alias and target are space separated. An example on a server with domain.tld as its domain:
# Alias delivered to an existing account
alias1@domain.tld user1@domain.tld
# Alias forwarded to an external email address
alias2@domain.tld external@gmail.com
Configuring RegExp Aliases
Additional regexp aliases can be configured by placing them into config/postfix-regexp.cf. The regexp aliases get evaluated after the virtual aliases (/tmp/docker-mailserver/postfix-virtual.cf). For example, the following config/postfix-regexp.cf causes all email to "test" users to be delivered to qa@example.com:
/^test[0-9][0-9]*@example.com/ qa@example.com
Address Tags (Extension Delimiters) an Alternative to Aliases
Postfix supports so-called address tags, in the form of plus (+) tags - i.e. address+tag@example.com will end up at address@example.com. This is configured by default and the (configurable !) separator is set to +. For more info, see How to use Address Tagging (user+tag@example.com) with Postfix and the official documentation.
!!! note
If you do decide to change the configurable separator, you must add the same line to both config/postfix-main.cf and config/dovecot.cf, because Dovecot is acting as the delivery agent. For example, to switch to -, add:
recipient_delimiter = -
