ONLYOFFICE Mail Server is a full-featured mail server solution developed on the base of the iRedMail package, containing the following components: Postfix, Dovecot, SpamAssassin, ClamAV, OpenDKIM, Fail2ban.

Integrated with ONLYOFFICE Community Server, Mail Server allows to:

• connect your own domain name;
• create mailboxes;
• add aliases for each mailbox;
• create mailbox groups.

• RAM: 4 GB or more
• CPU: dual-core 2 GHz or higher
• Swap file: at least 2 GB
• HDD: at least 2 GB of free space
• Distributive: 64-bit Red Hat, CentOS or other compatible distributive with kernel version 3.8 or later, 64-bit Debian, Ubuntu or other compatible distributive with kernel version 3.8 or later
• Docker: version 1.9.0 or later

sudo docker run --privileged -i -t -d -p 25:25 -p 143:143 -p 587:587 \
-h yourdomain.com onlyoffice/mailserver

Where yourdomain.com is your own domain name.

In this case the mail server will ensure the mail delivery to internal addresses hosted on this server.

To ensure the mail delivery to internal addresses as well as addresses of external servers you need to get your own domain name and configure a DNS server.

The following DNS records are required:

• A record (used to point a domain to the IP address of the host where this docker image is deployed).
• Pointer (RTP) record or a reverse DNS record (used to map a network interface (IP) to a hostname).

sudo docker run --privileged -i -t -d -p 25:25 -p 143:143 -p 587:587 \
-v /app/onlyoffice/MailServer/data/certs:/etc/pki/tls/mailserver -h yourdomain.com onlyoffice/mailserver

Where yourdomain.com is your own domain name.

The self-signed certificates for your domain will be created by default while running the docker container. If you want to use CA sertified certificates, you will need to rename them and copy into the /app/onlyoffice/MailServer/data/certs directory before running the image. The following files are required:

/app/onlyoffice/MailServer/data/certs/mail.onlyoffice.key
/app/onlyoffice/MailServer/data/certs/mail.onlyoffice.crt
/app/onlyoffice/MailServer/data/certs/mail.onlyoffice.ca-bundle

You can copy the SSL certificates into the /app/onlyoffice/MailServer/data/certs directory after running the image. But in this case you will need to restart the docker container.

Please refer the docker run command options for the --env-file flag where you can specify all required environment variables in a single file. This will save you from writing a potentially long docker run command.

Below is the complete list of parameters that can be set using environment variables.

• STORAGE_BASE_DIR: The path to the mail store. Defaults to /var/vmail.
• FIRST_DOMAIN: The first virtual domain, where the postmaster address will be hosted. This domain should not coincide with the primary mail server domain. Defaults to mailserver.onlyoffice.com.
• DOMAIN_ADMIN_PASSWD: The postmaster password. The default postmaster address is [email protected].

All the data are stored in the specially-designated directories, data volumes, at the following location:

• /var/log for ONLYOFFICE Mail Server logs
• /var/lib/mysql for MySQL database data
• /var/vmail for mail storage
• /etc/pki/tls/mailserver for certificates

To get access to your data from outside the container, you need to mount the volumes. It can be done by specifying the '-v' option in the docker run command.

sudo docker run --privileged -i -t -d -p 25:25 -p 143:143 -p 587:587 \
    -v /app/onlyoffice/MailServer/logs:/var/log  \
    -v /app/onlyoffice/MailServer/mysql:/var/lib/mysql  \
    -v /app/onlyoffice/MailServer/data:/var/vmail  \
    -v /app/onlyoffice/MailServer/data/certs:/etc/pki/tls/mailserver -h yourdomain.com onlyoffice/mailserver

Storing the data on the host machine allows you to easily update ONLYOFFICE once the new version is released without losing your data.

ONLYOFFICE Mail Server is a part of ONLYOFFICE Community Edition that comprises also Document Server and Community Server. To install them, follow these easy steps:

STEP 1: Create the 'onlyoffice' network.

docker network create --driver bridge onlyoffice

Than launch containers on it using the 'docker run --net onlyoffice' option:

STEP 1: Install ONLYOFFICE Document Server.

sudo docker run --net onlyoffice -i -t -d --restart=always --name onlyoffice-document-server \
	-v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data \
	-v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice \
	onlyoffice/documentserver

STEP 2: Install ONLYOFFICE Mail Server.

For the mail server correct work you need to specify its hostname 'yourdomain.com'.

sudo docker run --net onlyoffice --privileged -i -t -d --restart=always --name onlyoffice-mail-server \
	-p 25:25 -p 143:143 -p 587:587 \
	-v /app/onlyoffice/MailServer/data:/var/vmail \
	-v /app/onlyoffice/MailServer/data/certs:/etc/pki/tls/mailserver \
	-v /app/onlyoffice/MailServer/logs:/var/log \
	-v /app/onlyoffice/MailServer/mysql:/var/lib/mysql \
	-h yourdomain.com \
	onlyoffice/mailserver

STEP 3: Install ONLYOFFICE Community Server

sudo docker run --net onlyoffice -i -t -d --restart=always --name onlyoffice-community-server \
	-p 80:80 -p 5222:5222 -p 443:443 \
	-v /app/onlyoffice/CommunityServer/data:/var/www/onlyoffice/Data \
	-v /app/onlyoffice/CommunityServer/mysql:/var/lib/mysql \
	-v /app/onlyoffice/CommunityServer/logs:/var/log/onlyoffice \
	-v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/DocumentServerData \
	-e DOCUMENT_SERVER_PORT_80_TCP_ADDR=onlyoffice-document-server \
	-e MAIL_SERVER_DB_HOST=onlyoffice-mail-server \
	onlyoffice/communityserver

Alternatively, you can use an automatic installation script to install the whole ONLYOFFICE Community Edition at once. For the mail server correct work you need to specify its hostname 'yourdomain.com'.

STEP 1: Download the Community Edition Docker script file

wget http://download.onlyoffice.com/install/opensource-install.sh

STEP 2: Install ONLYOFFICE Community Edition executing the following command:

bash opensource-install.sh -md yourdomain.com

Or, use docker-compose. For the mail server correct work you need to specify its hostname 'yourdomain.com'. Assuming you have docker-compose installed, execute the following command:

wget https://raw.githubusercontent.com/ONLYOFFICE/Docker-CommunityServer/master/docker-compose.yml
docker-compose up -d
