"Brief" summary/overview of changes. See the PR discussion or individual commits from the PR for more details. --- Only applies to the `docs/content/**` content (_and `setup` command_). `target/` and `test/` can be normalized at a later date. * Normalize to `example.com` - Domains normalized to `example.com`: `mywebserver.com`, `myserver.tld`, `domain.com`, `domain.tld`, `mydomain.net`, `my-domain.tld`, `my-domain.com`, `example.org`, `whoami.com`. - Alternative domains normalized to `not-example.com`: `otherdomain.com`, `otherdomain.tld`, `domain2.tld`, `mybackupmx.com`, `whoareyou.org`. - Email addresses normalized to `admin@example.com` (in `ssl.md`): `foo@bar.com`, `yourcurrentemail@gmail.com`, `email@email.com`, `admin@domain.tld`. - Email addresses normalized to `external-account@gmail.com`: `bill@gates321boom.com`, `external@gmail.com`, `myemail@gmail.com`, `real-email-address@external-domain.com`. - **`faq.md`:** A FAQ entry title with `sample.domain.com` changed to `subdomain.example.com`. - **`mail-fetchmail.md`:** Config examples with FQDNs for `imap`/`pop3` used `example.com` domain for a third-party, changed to `gmail.com` as more familiar third-party/external MTA. * Normalize config volume path - Normalizing local config path references to `./docker-data/dms/config/`: `./config/`, `config/`, \``config`\`, `/etc/` (_volume mount src path prefix_). - Normalize DMS volume paths to `docker-data/dms/mail-{data,state,log}`: `./mail`, `./mail-state` `./data/mail`, `./data/state`, `./data/logs`, `./data/maildata`, `./data/mailstate`, `./data/maillogs`, (_dropped/converted data volumes: `maildata`, `mailstate`_). - Other docker images also adopt the `docker-data/{service name}/` prefix. * `ssl.md` - Use `dms/custom-certs` where appropriate. * Apply normalizations to README and example `docker-compose.yml` --- Common terms, sometimes interchangeably used or now invalid depending on context: `mail`, `mail container`, `mail server`, `mail-server`, `mailserver`,`docker-mailserver`, `Docker Mailserver`. Rough transformations applied to most matches (_conditionally, depending on context_): - 'Docker Mailserver' => '`docker-mailserver`' - 'mail container' => '`docker-mailserver`' (_optionally retaining ' container'_) - 'mail server' => 'mail-server' / '`docker-mailserver`' - 'mail-server' => '`docker-mailserver`' - 'mailserver' => 'mail-server' / '`docker-mailserver`' Additionally I checked `docker run` (_plus `exec`, `logs`, etc, sub-commands_) and `docker-compose` commands. Often finding usage of `mail` instead of the expected `mailserver` Additionally changes `mailserver` hostname in k8s to `mail` to align with other non-k8s examples. --- * drive-by revisions Mostly minor revisions or improvements to docs that aren't related to normalization effort.

title: 'Override the Default Configs | Dovecot'
|
||
---
|
||
|
||
## Add Configuration
|
||
|
||
The Dovecot default configuration can easily be extended providing a `docker-data/dms/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
|
||
├── docker-data/dms/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 `docker-mailserver` 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:
|
||
mailserver:
|
||
volumes:
|
||
- ./docker-data/dms/mail-data/:/var/mail/
|
||
- ./docker-data/dms/config/dovecot/10-master.conf:/etc/dovecot/conf.d/10-master.conf
|
||
```
|
||
|
||
You will first need to obtain the configuration from the running container (_where `mailserver` is the container name_):
|
||
|
||
```sh
|
||
mkdir -p ./docker-data/dms/config/dovecot
|
||
docker cp mailserver:/etc/dovecot/conf.d/10-master.conf ./docker-data/dms/config/dovecot/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 use the one matching your image version release.
|
||
|
||
The file `docker-data/dms/config/dovecot.cf` is copied internally to `/etc/dovecot/local.conf`. To verify the file content, run:
|
||
|
||
```sh
|
||
docker exec -it mailserver cat /etc/dovecot/local.conf
|
||
```
