|
|
|
|
A fullstack but simple mail server (smtp, imap, antispam, antivirus...).
|
|
Only configuration files, no SQL database. Keep it simple and versioned.
|
|
Easy to deploy and upgrade.
|
|
|
|
Includes:
|
|
|
|
- postfix with smtp or ldap auth
|
|
- dovecot for sasl, imap (and optional pop3) with ssl support, with ldap auth
|
|
- saslauthd with ldap auth
|
|
- amavis
|
|
- spamassasin supporting custom rules
|
|
- clamav with automatic updates
|
|
- opendkim
|
|
- opendmarc
|
|
- fail2ban
|
|
- fetchmail
|
|
- postgrey
|
|
- basic [sieve support](https://github.com/tomav/docker-mailserver/wiki/Configure-Sieve-filters) using dovecot
|
|
- [LetsEncrypt](https://letsencrypt.org/) and self-signed certificates
|
|
- persistent data and state (but think about backups!)
|
|
- [integration tests](https://travis-ci.org/tomav/docker-mailserver)
|
|
- [automated builds on docker hub](https://hub.docker.com/r/tvial/docker-mailserver/)
|
|
|
|
Why I created this image: [Simple mail server with Docker](http://tvi.al/simple-mail-server-with-docker/)
|
|
|
|
Before you open an issue, please have a look this `README`, the [Wiki](https://github.com/tomav/docker-mailserver/wiki/) and Postfix/Dovecot documentation.
|
|
|
|
## 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.
|
|
|
|
Your configs must be mounted in `/tmp/docker-mailserver/`. To understand how things work on boot, please have a look to [start-mailserver.sh](https://github.com/tomav/docker-mailserver/blob/master/target/start-mailserver.sh)
|
|
|
|
```yaml
|
|
version: '2'
|
|
|
|
services:
|
|
mail:
|
|
image: tvial/docker-mailserver:2.1
|
|
hostname: mail
|
|
domainname: domain.com
|
|
container_name: mail
|
|
ports:
|
|
- "25:25"
|
|
- "143:143"
|
|
- "587:587"
|
|
- "993:993"
|
|
volumes:
|
|
- maildata:/var/mail
|
|
- mailstate:/var/mail-state
|
|
- ./config/:/tmp/docker-mailserver/
|
|
environment:
|
|
- ENABLE_SPAMASSASSIN=1
|
|
- ENABLE_CLAMAV=1
|
|
- ENABLE_FAIL2BAN=1
|
|
- ENABLE_POSTGREY=1
|
|
- ONE_DIR=1
|
|
- DMS_DEBUG=0
|
|
cap_add:
|
|
- NET_ADMIN
|
|
|
|
volumes:
|
|
maildata:
|
|
driver: local
|
|
mailstate:
|
|
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.
|
|
|
|
Note: you can also manage email accounts, DKIM keys and more with the [setup.sh convenience script](https://github.com/tomav/docker-mailserver/wiki/Setup-docker-mailserver-using-the-script-setup.sh).
|
|
|
|
#### Start the container
|
|
|
|
docker-compose up -d mail
|
|
|
|
You're done!
|
|
|
|
## Environment variables
