--------------------------------------------------------------------
01. Continue with the following commands in a terminal window
# create main working directory
mkdir ~/docker/iRedMail -p
# create required sub-directories
mkdir ~/docker/iRedMail/data/{backup-mysql,clamav,custom,imapsieve_copy,mailboxes,mlmmj,mlmmj-archive,mysql,sa_rules,ssl,postfix_queue} -p
# create config file
touch ~/docker/iRedMail/iredmail-docker.conf
# write hostname to config
echo HOSTNAME=mail.i2bretro.net ≫≫ ~/docker/iRedMail/iredmail-docker.conf
echo FIRST_MAIL_DOMAIN=i12bretro.net ≫≫ ~/docker/iRedMail/iredmail-docker.conf
echo FIRST_MAIL_DOMAIN_ADMIN_PASSWORD=SomethingSecure ≫≫ ~/docker/iRedMail/iredmail-docker.conf
echo MLMMJADMIN_API_TOKEN=$(openssl rand -base64 32) ≫≫ ~/docker/iRedMail/iredmail-docker.conf
echo ROUNDCUBE_DES_KEY=$(openssl rand -base64 24) ≫≫ ~/docker/iRedMail/iredmail-docker.conf
# output the conf file and verify the values
cat ~/docker/iRedMail/iredmail-docker.conf
# set owner of working directories
sudo chown "$USER":"$USER" ~/docker -R
# run the iRedMail container
docker run -d --name iRedMail --env-file ~/docker/iRedMail/iredmail-docker.conf -p 80:80 -p 443:443 -p 110:110 -p 995:995 -p 143:143 -p 993:993 -p 25:25 -p 465:465 -p 587:587 -v ~/docker/iRedMail/data/backup-mysql:/var/vmail/backup/mysql -v ~/docker/iRedMail/data/mailboxes:/var/vmail/vmail1 -v ~/docker/iRedMail/data/mlmmj:/var/vmail/mlmmj -v ~/docker/iRedMail/data/mlmmj-archive:/var/vmail/mlmmj-archive -v ~/docker/iRedMail/data/imapsieve_copy:/var/vmail/imapsieve_copy -v ~/docker/iRedMail/data/custom:/opt/iredmail/custom -v ~/docker/iRedMail/data/ssl:/opt/iredmail/ssl -v ~/docker/iRedMail/data/mysql:/var/lib/mysql -v ~/docker/iRedMail/data/clamav:/var/lib/clamav -v ~/docker/iRedMail/data/sa_rules:/var/lib/spamassassin -v ~/docker/iRedMail/data/postfix_queue:/var/spool/postfix iredmail/mariadb:stable
