WildDuck itself is only an IMAP and POP3 server, with simple LMTP support if needed. However, because of its integration with ZoneMTA and Haraka, it can function as a complete mail server. Below are instructions for installing a complete mail server, or only WildDuck itself.
This method can be used on both new or existing servers, no matter the distro. If it supports docker, it will work (amd64 only right now, arm support will be added at a later time). Docker also makes updating or uninstalling all components quite easy.
The `docker-compose.yml` together with the default configuration script will set up all required dependencies and services, including Let's Encrypt based certs, to run WildDuck as a mail server.
To use the [default config](https://github.com/nodemailer/wildduck/blob/master/config/default.toml) file, run the following:
```
node server.js
```
Or if you want to override default configuration options with your own, run the following (custom config file is merged with the default, so specify only these
values that you want to change):
```
node server.js --config=/etc/wildduck.toml
```
> For additional config options, see the _wild-config_ [documentation](https://github.com/nodemailer/wild-config).
The easiest way to setup wildduck with a docker image is given below, for more documentation about configuration options in the docker image, refer to
the [in-depth page on the Docker](in-depth/docker.md).
A docker hub image built using the [Dockerfile](https://github.com/nodemailer/wildduck/blob/master/Dockerfile) in the repo is also available
To pull the latest pre-built image of wildduck:
```
docker pull nodemailer/wildduck
```
It is also possible to pull a specific version of wildduck by specifying the version as the image tag.
(example, for version 1.20):
```
docker pull nodemailer/wildduck:1.20
```
To run the docker image using the [default config](https://github.com/nodemailer/wildduck/blob/master/config/default.toml), and `mongodb` and `redis` from the host machine, use:
