## Pull requests
We gladly accept pull requests to add documentation, fix bugs and, in some circumstances,
add new features to Spree.
Here's a quick guide:
1. Fork the repo
2. Clone the fork to your local machine
3. Create new branch then make changes and add tests for your changes. Only
refactoring and documentation changes require no new tests. If you are adding
functionality or fixing a bug, we need tests!
4. Run the tests. `make build-no-cache generate-accounts run fixtures tests clean`
5. Push to your fork and submit a pull request. If the changes will apply cleanly
to the master branch, you will only need to submit one pull request.
Don't do pull requests against `-stable` branches. Always target the master branch. Any bugfixes we'll backport to those branches.
At this point, you're waiting on us. We like to at least comment on, if not
accept, pull requests within several days.
We may suggest some changes or improvements or alternatives.
Some things that will increase the chance that your pull request is accepted.
Syntax:
* Two spaces, no tabs.
* No trailing whitespace. Blank lines should not have any space.
* Follow the conventions you see used in the source already.
* Alphabetize the class methods to keep them organized
And in case we didn't emphasize it enough: we love tests!

# Contributing
`docker-mailserver` is OpenSource. That means that you can contribute on enhancements, bug fixing or improving the documentation in the Wiki.
This project is Open Source. That means that you can contribute on enhancements, bug fixing or improving the documentation in the [Wiki](https://github.com/docker-mailserver/docker-mailserver/wiki).
1. [Issues & PRs](#issues--prs)
1. [Opening an Issue](#opening-an-issue)
@ -23,20 +23,18 @@ You want to add a feature? Feel free to start creating an issue explaining what
The development workflow is the following:
- Fork the project and clone your fork
- Create a branch using `git checkout -b branch_name` (you can use `issue-xxx` if fixing an existing issue)
- Run `git submodule init` and `git submodule update` to get the BATS submodules
- Code :-)
- Add integration tests in `test/tests.bats`
- Use `make clean all` to build image locally and run tests
Note that tests work on Linux only; they hang on Mac and Windows.
- Document your improvements in `README.md` or Wiki depending on content
- [Commit][commit], if possible with [signing your commit with a GPG key][gpg], push and make a pull-request
- Pull-request is automatically tested on Travis
- When tests are green, a review may be done
- When changed are validated, your branch is merged into `master`
- `master` is automatically tested on Travis
- Docker builds a new `latest` image
1. Fork the project and clone your fork
1. Create a new branch to work on
2. Run `git submodule update --init --recursive`
2. Write the code that is needed :D
3. Add integration tests if necessary
4. Get the linters with `make install_linters`
5. Use `make clean all` to build image locally and run tests (note that tests work on Linux **only**)
6. Document your improvements if necessary (e.g. if you introduced new environment variables, write the description in [`ENVIRONMENT.md`](./ENVIRONMENT.md))
7. [Commit][commit] and [sign your commit][gpg], push and create a pull-request to merge into `master`
1. Pull requests are automatically tested against the CI and will be reviewed when tests pass
2. When your changes are validated, your branch is merged
3. CI builds the new `:latest` image

# Environment
## Variables
1. If an option doesn't work as documented here, check if you are running the latest image!
2. Values in **bold** are the default values.
3. Since `docker-mailserver v7.1.0`, comparisons for environment variables are executed differently. If you previously used `VARIABLE=''` as the `empty` value, **update** to now use `VARIABLE=`.
### Assignments
#### General
##### DMS_DEBUG
- **0** => Debug disabled
- 1 => Enables debug on startup
##### ENABLE_CLAMAV
- **0** => Clamav is disabled
- 1 => Clamav is enabled
##### ONE_DIR
- **0** => state in default directories
- 1 => consolidate all states into a single directory (`/var/mail-state`) to allow persistence using docker volumes
##### ENABLE_POP3
- **empty** => POP3 service disabled
- 1 => Enables POP3 service
##### ENABLE_FAIL2BAN
- **0** => fail2ban service disabled
- 1 => Enables fail2ban service
If you enable Fail2Ban, don't forget to add the following lines to your `docker-compose.yml`:
``` BASH
cap_add:
- NET_ADMIN
```
Otherwise, `iptables` won't be able to ban IPs.
##### SMTP_ONLY
- **empty** => all daemons start
- 1 => only launch postfix smtp
##### SSL_TYPE
- **empty** => SSL disabled
- letsencrypt => Enables Let's Encrypt certificates
- custom => Enables custom certificates
- manual => Let you manually specify locations of your SSL certificates for non-standard cases
- self-signed => Enables self-signed certificates
- _any other value_ => SSL required, settings by default
Please read [the SSL page in the wiki](https://github.com/tomav/docker-mailserver/wiki/Configure-SSL) for more information.
##### TLS_LEVEL
- **empty** => modern
- modern => Enables TLSv1.2 and modern ciphers only. (default)
- intermediate => Enables TLSv1, TLSv1.1 and TLSv1.2 and broad compatibility ciphers.
- old => NOT implemented. If you really need it, then customize the TLS ciphers overriding postfix and dovecot settings [wiki](https://github.com/tomav/docker-mailserver/wiki/)
##### SPOOF_PROTECTION
Configures the handling of creating mails with forged sender addresses.
- **empty** => Mail address spoofing allowed. Any logged in user may create email messages with a forged sender address. See also [Wikipedia](https://en.wikipedia.org/wiki/Email_spoofing)(not recommended, but default for backwards compatibility reasons)
- 1 => (recommended) Mail spoofing denied. Each user may only send with his own or his alias addresses. Addresses with [extension delimiters](http://www.postfix.org/postconf.5.html#recipient_delimiter) are not able to send messages.
##### ENABLE_SRS
Enables the Sender Rewriting Scheme. SRS is needed if your mail server acts as forwarder. See [postsrsd](https://github.com/roehling/postsrsd/blob/master/README.md#sender-rewriting-scheme-crash-course) for further explanation.
- **0** => Disabled
- 1 => Enabled
##### PERMIT_DOCKER
Set different options for mynetworks option (can be overwrite in postfix-main.cf) **WARNING**: Adding the docker network's gateway to the list of trusted hosts, e.g. using the `network` or `connected-networks` option, can create an [**open relay**](https://en.wikipedia.org/wiki/Open_mail_relay), for instance if IPv6 is enabled on the host machine but not in Docker.
- **empty** => localhost only
- host => Add docker host (ipv4 only)
- network => Add the docker default bridge network (172.16.0.0/12); **WARNING**: `docker-compose` might use others (e.g. 192.168.0.0/16) use `PERMIT_DOCKER=connected-networks` in this case
- connected-networks => Add all connected docker networks (ipv4 only)
Note: you probably want to [set `POSTFIX_INET_PROTOCOLS=ipv4`](#postfix_inet_protocols) to make it work fine with Docker.
##### NETWORK_INTERFACE
In case your network interface differs from `eth0`, e.g. when you are using HostNetworking in Kubernetes, you can set this to whatever interface you want. This interface will then be used.
- **empty** => `eth0`
##### VIRUSMAILS_DELETE_DELAY
Set how many days a virusmail will stay on the server before being deleted
- **empty** => 7 days
##### ENABLE_POSTFIX_VIRTUAL_TRANSPORT
This Option is activating the Usage of POSTFIX_DAGENT to specify a ltmp client different from default dovecot socket.
- **empty** => disabled
- 1 => enabled
##### POSTFIX_DAGENT
Enabled by ENABLE_POSTFIX_VIRTUAL_TRANSPORT. Specify the final delivery of postfix
- **empty**: fail
- `lmtp:unix:private/dovecot-lmtp` (use socket)
- `lmtps:inet:<host>:<port>` (secure lmtp with starttls, take a look at <https://sys4.de/en/blog/2014/11/17/sicheres-lmtp-mit-starttls-in-dovecot/>)
- `lmtp:<kopano-host>:2003` (use kopano as mailstore)
- etc.

- **empty** => 10240000 (~10 MB)
##### ENABLE_MANAGESIEVE
- **empty** => Managesieve service disabled
- 1 => Enables Managesieve on port 4190
##### OVERRIDE_HOSTNAME
- **empty** => uses the `hostname` command to get the mail server's canonical hostname
- => Specify a fully-qualified domainname to serve mail for. This is used for many of the config features so if you can't set your hostname (e.g. you're in a container platform that doesn't let you) specify it in this environment variable.
##### POSTMASTER_ADDRESS
- **empty** => postmaster@domain.com
- => Specify the postmaster address
##### POSTSCREEN_ACTION
- **enforce** => Allow other tests to complete. Reject attempts to deliver mail with a 550 SMTP reply, and log the helo/sender/recipient information. Repeat this test the next time the client connects.
- drop => Drop the connection immediately with a 521 SMTP reply. Repeat this test the next time the client connects.
- ignore => Ignore the failure of this test. Allow other tests to complete. Repeat this test the next time the client connects. This option is useful for testing and collecting statistics without blocking mail.
##### DOVECOT_MAILBOX_FORMAT
- **maildir** => uses very common Maildir format, one file contains one message
- sdbox => (experimental) uses Dovecot high-performance mailbox format, one file contains one message
- mdbox ==> (experimental) uses Dovecot high-performance mailbox format, multiple messages per file and multiple files per box
This option has been added in November 2019. Using other format than Maildir is considered as experimental in docker-mailserver and should only be used for testing purpose. For more details, please refer to [Dovecot Documentation](https://wiki2.dovecot.org/MailboxFormat).
##### POSTFIX_INET_PROTOCOLS
- **all** => All possible protocols.
- ipv4 => Use only IPv4 traffic. Most likely you want this behind Docker.
- ipv6 => Use only IPv6 traffic.
Note: More details in <http://www.postfix.org/postconf.5.html#inet_protocols>
#### Reports
##### PFLOGSUMM_TRIGGER
Enables regular pflogsumm mail reports.
- **not set** => No report
- daily_cron => Daily report for the previous day
- logrotate => Full report based on the mail log when it is rotated
This is a new option. The old REPORT options are still supported for backwards compatibility.
If this is not set and reports are enabled with the old options, logrotate will be used.
##### PFLOGSUMM_RECIPIENT
Recipient address for pflogsumm reports.
- **not set** => Use REPORT_RECIPIENT or POSTMASTER_ADDRESS
- => Specify the recipient address(es)
##### PFLOGSUMM_SENDER
From address for pflogsumm reports.
- **not set** => Use REPORT_SENDER or POSTMASTER_ADDRESS
- => Specify the sender address
##### LOGWATCH_INTERVAL
Interval for logwatch report.
- **none** => No report is generated
- daily => Send a daily report
- weekly => Send a report every week
##### LOGWATCH_RECIPIENT
Recipient address for logwatch reports if they are enabled.
- **not set** => Use REPORT_RECIPIENT or POSTMASTER_ADDRESS
- => Specify the recipient address(es)
##### REPORT_RECIPIENT (deprecated)
Enables a report being sent (created by pflogsumm) on a regular basis.
- **0** => Report emails are disabled unless enabled by other options
- 1 => Using POSTMASTER_ADDRESS as the recipient
- => Specify the recipient address
##### REPORT_SENDER (deprecated)
Change the sending address for mail report
- **empty** => mailserver-report@hostname
- => Specify the report sender (From) address
##### REPORT_INTERVAL (deprecated)
Changes the interval in which logs are rotated and a report is being sent (deprecated).
- **daily** => Send a daily report
- weekly => Send a report every week
- monthly => Send a report every month
Note: This variable used to control logrotate inside the container and sent the pflogsumm report when the logs were rotated.
It is still supported for backwards compatibility, but the new option LOGROTATE_INTERVAL has been added that only rotates
the logs.
##### LOGROTATE_INTERVAL
Defines the interval in which the mail log is being rotated.
- **daily** => Rotate daily.
- weekly => Rotate weekly.
- monthly => Rotate monthly.
Note that only the log inside the container is affected.
The full log output is still available via `docker logs mail` (or your respective container name).
If you want to control logrotation for the docker generated logfile see: [Docker Logging Drivers](https://docs.docker.com/config/containers/logging/configure/).
Also note that by default the logs are lost when the container is recycled. To keep the logs, mount a volume.
Finally the logrotate interval **may** affect the period for generated reports. That is the case when the reports are triggered by log rotation.
#### Spamassassin
##### ENABLE_SPAMASSASSIN
- **0** => Spamassassin is disabled
- 1 => Spamassassin is enabled
**/!\\ Spam delivery:** when Spamassassin is enabled, messages marked as spam WILL NOT BE DELIVERED.

Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`
##### SA_KILL
- **6.31** => triggers spam evasive actions
Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`. By default, the mailserver is configured to quarantine spam emails. If emails are quarantined, they are compressed and stored in a location dependent on the ONE_DIR setting above. If `ONE_DIR=1` the location is /var/mail-state/lib-amavis/virusmails/. If `ONE_DIR=0` it is /var/lib/amavis/virusmails/. These paths are inside the docker container. To inhibit this behaviour and deliver spam emails, set this to a very high value e.g. 100.0.
##### SA_SPAM_SUBJECT
- **\*\*\*SPAM\*\*\*** => add tag to subject if spam detected
Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`. Add the spamassassin score to the subject line by inserting the keyword _SCORE_: **\*\*\*SPAM(_SCORE_)\*\*\***.
##### SA_SHORTCIRCUIT_BAYES_SPAM

##### SPOOF_PROTECTION
Configures the handling of creating mails with forged sender addresses.
- **empty** => Mail address spoofing allowed. Any logged in user may create email messages with a forged sender address. See also [Wikipedia](https://en.wikipedia.org/wiki/Email_spoofing)(not recommended, but default for backwards compatibility reasons)

- **0** => Disabled
- 1 => Enabled
##### PERMIT_DOCKER
Set different options for mynetworks option (can be overwrite in postfix-main.cf) **WARNING**: Adding the docker network's gateway to the list of trusted hosts, e.g. using the `network` or `connected-networks` option, can create an [**open relay**](https://en.wikipedia.org/wiki/Open_mail_relay), [for instance](https://github.com/tomav/docker-mailserver/issues/1405#issuecomment-590106498) if IPv6 is enabled on the host machine but not in Docker.
- **empty** => localhost only
- host => Add docker host (ipv4 only)
- network => Add the docker default bridge network (172.16.0.0/12); **WARNING**: `docker-compose` might use others (e.g. 192.168.0.0/16) use `PERMIT_DOCKER=connected-networks` in this case
- connected-networks => Add all connected docker networks (ipv4 only)
Note: you probably want to [set `POSTFIX_INET_PROTOCOLS=ipv4`](#postfix_inet_protocols) to make it work fine with Docker.
##### NETWORK_INTERFACE
In case your network interface differs from `eth0`, e.g. when you are using HostNetworking in Kubernetes, you can set this to whatever interface you want. This interface will then be used.
- **empty** => `eth0`
##### VIRUSMAILS_DELETE_DELAY
Set how many days a virusmail will stay on the server before being deleted
- **empty** => 7 days
##### ENABLE_POSTFIX_VIRTUAL_TRANSPORT
This Option is activating the Usage of POSTFIX_DAGENT to specify a ltmp client different from default dovecot socket.
- **empty** => disabled
- 1 => enabled
##### POSTFIX_DAGENT
Enabled by ENABLE_POSTFIX_VIRTUAL_TRANSPORT. Specify the final delivery of postfix
- **empty**: fail
- `lmtp:unix:private/dovecot-lmtp` (use socket)

- `lmtp:<kopano-host>:2003` (use kopano as mailstore)
- etc.
##### POSTFIX\_MAILBOX\_SIZE\_LIMIT
Set the mailbox size limit for all users. If set to zero, the size will be unlimited (default).
- **empty** => 0 (no limit)
##### ENABLE_QUOTAS
- **1** => Dovecot quota is enabled
- 0 => Dovecot quota is disabled
See [mailbox quota](https://github.com/tomav/docker-mailserver/wiki/Configure-Accounts#mailbox-quota).
##### POSTFIX\_MESSAGE\_SIZE\_LIMIT
Set the message size limit for all users. If set to zero, the size will be unlimited (not recommended!)
- **empty** => 10240000 (~10 MB)
##### ENABLE_MANAGESIEVE
- **empty** => Managesieve service disabled
- 1 => Enables Managesieve on port 4190
##### OVERRIDE_HOSTNAME
- **empty** => uses the `hostname` command to get the mail server's canonical hostname
- => Specify a fully-qualified domainname to serve mail for. This is used for many of the config features so if you can't set your hostname (e.g. you're in a container platform that doesn't let you) specify it in this environment variable.
##### POSTMASTER_ADDRESS
- **empty** => postmaster@domain.com
- => Specify the postmaster address
##### POSTSCREEN_ACTION
- **enforce** => Allow other tests to complete. Reject attempts to deliver mail with a 550 SMTP reply, and log the helo/sender/recipient information. Repeat this test the next time the client connects.
- drop => Drop the connection immediately with a 521 SMTP reply. Repeat this test the next time the client connects.
- ignore => Ignore the failure of this test. Allow other tests to complete. Repeat this test the next time the client connects. This option is useful for testing and collecting statistics without blocking mail.
##### DOVECOT_MAILBOX_FORMAT
- **maildir** => uses very common Maildir format, one file contains one message
- sdbox => (experimental) uses Dovecot high-performance mailbox format, one file contains one message
- mdbox ==> (experimental) uses Dovecot high-performance mailbox format, multiple messages per file and multiple files per box
This option has been added in November 2019. Using other format than Maildir is considered as experimental in docker-mailserver and should only be used for testing purpose. For more details, please refer to [Dovecot Documentation](https://wiki2.dovecot.org/MailboxFormat).
##### POSTFIX_INET_PROTOCOLS
- **all** => All possible protocols.
- ipv4 => Use only IPv4 traffic. Most likely you want this behind Docker.
- ipv6 => Use only IPv6 traffic.
Note: More details in <http://www.postfix.org/postconf.5.html#inet_protocols>
#### Reports
##### PFLOGSUMM_TRIGGER
Enables regular pflogsumm mail reports.
- **not set** => No report
- daily_cron => Daily report for the previous day
- logrotate => Full report based on the mail log when it is rotated
This is a new option. The old REPORT options are still supported for backwards compatibility.
If this is not set and reports are enabled with the old options, logrotate will be used.
##### PFLOGSUMM_RECIPIENT
Recipient address for pflogsumm reports.
- **not set** => Use REPORT_RECIPIENT or POSTMASTER_ADDRESS
- => Specify the recipient address(es)
##### PFLOGSUMM_SENDER
From address for pflogsumm reports.
- **not set** => Use REPORT_SENDER or POSTMASTER_ADDRESS
- => Specify the sender address
##### LOGWATCH_INTERVAL
Interval for logwatch report.
- **none** => No report is generated
- daily => Send a daily report
- weekly => Send a report every week
##### LOGWATCH_RECIPIENT
Recipient address for logwatch reports if they are enabled.
- **not set** => Use REPORT_RECIPIENT or POSTMASTER_ADDRESS
- => Specify the recipient address(es)
##### REPORT_RECIPIENT (deprecated)
Enables a report being sent (created by pflogsumm) on a regular basis.
- **0** => Report emails are disabled unless enabled by other options
- 1 => Using POSTMASTER_ADDRESS as the recipient
- => Specify the recipient address
##### REPORT_SENDER (deprecated)
Change the sending address for mail report
- **empty** => mailserver-report@hostname
- => Specify the report sender (From) address
##### REPORT_INTERVAL (deprecated)
Changes the interval in which logs are rotated and a report is being sent (deprecated).
- **daily** => Send a daily report
- weekly => Send a report every week
- monthly => Send a report every month
Note: This variable used to control logrotate inside the container and sent the pflogsumm report when the logs were rotated.
It is still supported for backwards compatibility, but the new option LOGROTATE_INTERVAL has been added that only rotates
the logs.
##### LOGROTATE_INTERVAL
Defines the interval in which the mail log is being rotated.
- **daily** => Rotate daily.
- weekly => Rotate weekly.
- monthly => Rotate monthly.
Note that only the log inside the container is affected.
The full log output is still available via `docker logs mail` (or your respective container name).
If you want to control logrotation for the docker generated logfile see: [Docker Logging Drivers](https://docs.docker.com/config/containers/logging/configure/).
Also note that by default the logs are lost when the container is recycled. To keep the logs, mount a volume.
Finally the logrotate interval **may** affect the period for generated reports. That is the case when the reports are triggered by log rotation.
#### Spamassassin
##### ENABLE_SPAMASSASSIN
- **0** => Spamassassin is disabled
- 1 => Spamassassin is enabled
**/!\\ Spam delivery:** when Spamassassin is enabled, messages marked as spam WILL NOT BE DELIVERED.
Use `SPAMASSASSIN_SPAM_TO_INBOX=1` for receiving spam messages.
##### SPAMASSASSIN_SPAM_TO_INBOX
- **0** => Spam messages will be bounced (_rejected_) without any notification (_dangerous_).
- 1 => Spam messages will be delivered to the inbox and tagged as spam using `SA_SPAM_SUBJECT`.
##### MOVE_SPAM_TO_JUNK
- **1** => Spam messages will be delivered in the `Junk` folder.
- 0 => Spam messages will be delivered in the mailbox.
Note: this setting needs `SPAMASSASSIN_SPAM_TO_INBOX=1`
##### SA_TAG
- **2.0** => add spam info headers if at, or above that level
Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`
##### SA_TAG2
- **6.31** => add 'spam detected' headers at that level
Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`
##### SA_KILL
- **6.31** => triggers spam evasive actions
Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`. By default, the mailserver is configured to quarantine spam emails. If emails are quarantined, they are compressed and stored in a location dependent on the ONE_DIR setting above. If `ONE_DIR=1` the location is /var/mail-state/lib-amavis/virusmails/. If `ONE_DIR=0` it is /var/lib/amavis/virusmails/. These paths are inside the docker container. To inhibit this behaviour and deliver spam emails, set this to a very high value e.g. 100.0.
##### SA_SPAM_SUBJECT
- **\*\*\*SPAM\*\*\*** => add tag to subject if spam detected
Note: this spamassassin setting needs `ENABLE_SPAMASSASSIN=1`. Add the spamassassin score to the subject line by inserting the keyword _SCORE_: **\*\*\*SPAM(_SCORE_)\*\*\***.
##### SA_SHORTCIRCUIT_BAYES_SPAM
- **1** => will activate spamassassin short circuiting for bayes spam detection.
This will uncomment the respective line in ```/etc/spamassasin/local.cf```
Note: activate this only if you are confident in your bayes database for identifying spam.
##### SA_SHORTCIRCUIT_BAYES_HAM
- **1** => will activate spamassassin short circuiting for bayes ham detection
This will uncomment the respective line in ```/etc/spamassasin/local.cf```
Note: activate this only if you are confident in your bayes database for identifying ham.
#### Fetchmail

- empty => None
- e.g. with SASLAUTHD_MECHANISMS rimap you need to specify the ip-address/servername of the imap server ==> xxx.xxx.xxx.xxx
##### SASLAUTHD_LDAP_SERVER
- empty => localhost
##### SASLAUTHD_LDAP_SSL
- empty or 0 => `ldap://` will be used
- 1 => `ldaps://` will be used

#### SRS (Sender Rewriting Scheme)
##### SRS_SENDER_CLASSES
An email has an "envelope" sender (indicating the sending server) and a
"header" sender (indicating who sent it). More strict SPF policies may require
you to replace both instead of just the envelope sender.
[More info](https://www.mybluelinux.com/what-is-email-envelope-and-email-header/).
- **envelope_sender** => Rewrite only envelope sender address
- header_sender => Rewrite only header sender (not recommended)
- envelope_sender,header_sender => Rewrite both senders
##### SRS_EXCLUDE_DOMAINS
- **empty** => Envelope sender will be rewritten for all domains
- provide comma separated list of domains to exclude from rewriting
##### SRS_SECRET
- **empty** => generated when the container is started for the first time
- provide a secret to use in base64
- you may specify multiple keys, comma separated. the first one is used for signing and the remaining will be used for verification. this is how you rotate and expire keys
- if you have a cluster/swarm make sure the same keys are on all nodes
- example command to generate a key: `dd if=/dev/urandom bs=24 count=1 2>/dev/null | base64`
##### SRS_DOMAINNAME
- **empty** => Derived from OVERRIDE_HOSTNAME, DOMAINNAME, or the container's hostname
- Set this if auto-detection fails, isn't what you want, or you wish to have a separate container handle DSNs
