## Usage
#### Get latest image
docker pull tvial/docker-mailserver:latest
#### Create a `docker-compose.yml`
Adapt this file with your FQDN. Install [docker-compose](https://docs.docker.com/compose/) in the version `1.6` or higher.
version: '2'
services:
mail:
image: tvial/docker-mailserver:latest
# build: .
hostname: mail
domainname: domain.com
container_name: mail
ports:
- "25:25"
- "143:143"
- "587:587"
- "993:993"
volumes:
- maildata:/var/mail
- ./config/:/tmp/docker-mailserver/
volumes:
maildata:
driver: local
#### Create your mail accounts
Don't forget to adapt MAIL_USER and MAIL_PASS to your needs
mkdir -p config
touch config/postfix-accounts.cf
docker run --rm \
-e MAIL_USER=user1@domain.tld \
-e MAIL_PASS=mypassword \
-ti tvial/docker-mailserver:latest \
/bin/sh -c 'echo "$MAIL_USER|$(doveadm pw -s SHA512-CRYPT -u $MAIL_USER -p $MAIL_PASS)"' >> config/postfix-accounts.cf
#### Generate DKIM keys
docker run --rm \
-v "$(pwd)/config":/tmp/docker-mailserver \
-ti tvial/docker-mailserver:latest generate-dkim-config
Now the keys are generated, you can configure your DNS server by just pasting the content of `config/opendkim/keys/domain.tld/mail.txt` in your `domain.tld.hosts` zone.
#### Start the container
docker-compose up -d mail
You're done!
