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.
|
|
|
|
You will need to first obtain the configuration from the running container: `mkdir -p ./config/dovecot && docker cp mailserver:/etc/dovecot/conf.d/10-master.conf ./config/dovecot/10-master.conf`
|
|
|
|
```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 mailserver doveconf | grep <some-keyword>`
|
|
|
|
!!! note
|
|
[`setup.sh`][github-file-setupsh] is included in the `docker-mailserver` repository. Make sure to grap the one matching your image version.
|
|
|
|
The `config/dovecot.cf` is copied internally to `/etc/dovecot/local.conf`. To check this file run:
|
|
|
|
```sh
|
|
docker exec -it mailserver cat /etc/dovecot/local.conf
|
|
```
|
