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.

title: 'Override the Default Configs | Dovecot'
|
||
---
|
||
|
||
## Add Configuration
|
||
|
||
The Dovecot default configuration can easily be extended providing a `config/dovecot.cf` file.
|
||
[Dovecot documentation](https://wiki.dovecot.org) remains the best place to find configuration options.
|
||
|
||
Your `docker-mailserver` folder should look like this example:
|
||
|
||
```txt
|
||
├── config
|
||
│ ├── dovecot.cf
|
||
│ ├── postfix-accounts.cf
|
||
│ └── postfix-virtual.cf
|
||
├── docker-compose.yml
|
||
└── README.md
|
||
```
|
||
|
||
One common option to change is the maximum number of connections per user:
|
||
|
||
```cf
|
||
mail_max_userip_connections = 100
|
||
```
|
||
|
||
Another important option is the `default_process_limit` (defaults to `100`). If high-security mode is enabled you'll need to make sure this count is higher than the maximum number of users that can be logged in simultaneously.
|
||
|
||
This limit is quickly reached if users connect to the mail server with multiple end devices.
|
||
|
||
## Override Configuration
|
||
|
||
For major configuration changes it’s best to override the dovecot configuration files. For each configuration file you want to override, add a list entry under the `volumes` key.
|
||
|
||
```yaml
|
||
services:
|
||
mail:
|
||
volumes:
|
||
- maildata:/var/mail
|
||
- ./config/dovecot/10-master.conf:/etc/dovecot/conf.d/10-master.conf
|
||
```
|
||
|
||
## Debugging
|
||
|
||
To debug your dovecot configuration you can use:
|
||
|
||
- This command: `./setup.sh debug login doveconf | grep <some-keyword>`
|
||
- Or: `docker exec -it <your-container-name> doveconf | grep <some-keyword>`
|
||
|
||
!!! note
|
||
[`setup.sh`][github-file-setupsh] is included in the `docker-mailserver` repository.
|
||
|
||
The `config/dovecot.cf` is copied internally to `/etc/dovecot/local.conf`. To check this file run:
|
||
|
||
```sh
|
||
docker exec -it <your-container-name> cat /etc/dovecot/local.conf
|
||
```
