### What kind of database are you using?
|
|
None. No *sql database required.
|
|
This image is based on config files that can be versioned.
|
|
You'll probably want to `push` your config updates to your server and restart the container to apply changes.
|
|
|
|
### Where are emails stored?
|
|
Mails are stored in `/var/mail/${domain}/${username}`.
|
|
You should use a [data volume container](https://medium.com/@ramangupta/why-docker-data-containers-are-good-589b3c6c749e#.uxyrp7xpu) for `/var/mail` for data persistence. Otherwise, your data may be lost.
|
|
|
|
### How can I use data volume container as proposed above?
|
|
|
|
Here is a `docker-compose.yml` example which use a data volume container for email storage named `maildata`.
|
|
|
|
maildata:
|
|
image: ubuntu
|
|
volumes:
|
|
- /var/mail
|
|
command: /bin/true
|
|
|
|
mail:
|
|
image: "tvial/docker-mailserver"
|
|
hostname: "mail"
|
|
domainname: "domain.com"
|
|
volumes_from:
|
|
- maildata
|
|
ports:
|
|
- "25:25"
|
|
- "143:143"
|
|
- "587:587"
|
|
- "993:993"
|
|
volumes:
|
|
- ./spamassassin:/tmp/spamassassin/
|
|
- ./postfix:/tmp/postfix/
|
|
- ./opendkim/keys:/etc/opendkim/keys
|
|
- ./letsencrypt/etc:/etc/letsencrypt
|
|
environment:
|
|
- DMS_SSL=letsencrypt
|
|
|
|
### What about backups?
|
|
|
|
Assuming that you use `docker-compose` and a data volume container named `maildata`, you can backup your user mails like this:
|
|
|
|
docker run --rm \
|
|
--volumes-from maildata_1 \
|
|
-v "$(pwd)":/backups \
|
|
-ti tvial/docker-mailserver \
|
|
tar cvzf /backups/docker-mailserver-`date +%y%m%d-%H%M%S`.tgz /var/mail
|
|
|
|
### How can I configure my email client?
|
|
Login are full email address (`user@domain.com`).
|
|
Both login and password are managed in `postfix/accounts.cf` file.
|
|
Please have a look to the `README` in order to manage users and aliases.
|
|
|
|
# imap
|
|
username: <user1@domain.tld>
|
|
password: <mypassword>
|
|
server: <mail.domain.tld>
|
|
imap port: 143 or 993 with ssl (recommended)
|
|
imap path prefix: INBOX
|
|
|
|
# smtp
|
|
smtp port: 25 or 587 with ssl (recommended)
|
|
username: <user1@domain.tld>
|
|
password: <mypassword>
|
|
|
|
### How can I manage my custom Spamassassin rules?
|
|
Antispam rules are managed in `spamassassin/rules.cf`.
|
|
|
|
### What kind of SSL certificates can I use?
|
|
You can use the same certificates you use with another mail server.
|
|
The only thing is that we provide a `self-signed` certificate tool and a `letsencrypt` certificate loader. |
