docs(chore): Normalize for consistency (#2206)
"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.

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 its 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
```
