This image provides a secure mail server based on:
All incoming mail to your domains is accepted. For outgoing mail, only authenticated (logged in with username and password) clients can send messages via STARTTLS.
You will need 2 folder on your host, one to store your configuration and another one to store your email. In the instructions below we will use the following:
/var/lib/dockermail/settings
to store configuration/var/lib/dockermail/vmail
to store the mailUse the the example config files in config/example
to get you started.
Add all domains you want to receive mail for to the file /var/lib/dockermail/settings/domains
, like this:
example.org
example.net
Add user aliases to the file /var/lib/dockermail/settings/aliases
:
johndoe@example.org john.doe@example.org
john.doe@example.org john.doe@example.org
admin@forum.example.org forum-admin@example.org
@example.net catch-all@example.net
An IMAP mail account is created for each entry on the right hand side. Every mail sent to one of the addresses in the left column will be delivered to the corresponding account in the right column.
Add user passwords to the file /var/lib/dockermail/settings/passwords
like this
john.doe@example.org:{PLAIN}password123
admin@example.org:{SHA256-CRYPT}$5$ojXGqoxOAygN91er$VQD/8dDyCYOaLl2yLJlRFXgl.NSrB3seZGXBRMdZAr6
To get the hash values, you can either install dovecot locally or use docker exec -it [email_core_container_name] bash
to attach to the running container (step 6) and run doveadm pw -s <scheme-name>
inside, remember to restart your container if you update the settings!
Change the hostname in file /var/lib/dockermail/settings/myhostname
to the correct fully qualified domain of your server.
Set the “mynetworks” variable for postfix in file /var/lib/dockermail/settings/postfix-networks
to e.g. 127.0.0.0/8 [::1]/128
(one single line only).
Build container
docker build -t hasufell/exherbo-dockermail .
Run container
docker run -ti -d \
--name dockermail \
-p 25:25 \
-p 465:465 \
-p 993:993 \

-v /var/lib/dockermail/settings:/mail_settings \
-v /var/lib/dockermail/vmail:/vmail \
-v <path-to-certs>:/etc/ssl/server
