# Add configuration
|
||
|
||
The Dovecot default configuration can easily be extended providing a `config/dovecot.cf` file.
|
||
[Dovecot documentation](http://wiki.dovecot.org/FrontPage) remains the best place to find configuration options.
|
||
|
||
Your `docker-mailserver` folder should look like this example:
|
||
|
||
```
|
||
├── 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:
|
||
|
||
```
|
||
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.
|
||
|
||
# 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
|
||
version: '2'
|
||
|
||
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:
|
||
|
||
```sh
|
||
./setup.sh debug login doveconf | grep <some-keyword>
|
||
```
|
||
|
||
[setup.sh](https://github.com/tomav/docker-mailserver/blob/master/setup.sh) is included in the `docker-mailserver` repository.
|
||
|
||
or
|
||
|
||
```sh
|
||
docker exec -ti <your-container-name> doveconf | grep <some-keyword>
|
||
```
|
||
|
||
The `config/dovecot.cf` is copied to `/etc/dovecot/local.conf`. To check this file run:
|
||
|
||
```sh
|
||
docker exec -ti <your-container-name> cat /etc/dovecot/local.conf
|
||
```
