## 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.
|
|

docker-compose up -d mail

You're done!
