* Added DEFAULT_RELAY_HOST setting
* If set this value will be used as the relayhost in /etc/postfix/maincf causing all mail to be delivered using this relay host
* Test for default relay host setting
* DOMAINNAME can fail to be set in postsrsd-wrapper.sh
if the container doesn’t have a proper hostname, postsrsd will fail to start
because SRS_DOMAIN is empty. Make a best effort to figure out the domain name
and provide a way to set one if needed.
This modification proposes to support the running configured mounted
volume for configuration.
This removes the need to pass a path from the command line when the
container is running and configured in another way that yours.
* Ensure that the provided username actually contains a domain
* Update README.md to be consistent with addmailuser script
* Add a test to check if the username includes the domain
* Add new configuration for multi-domain relay hosts (#922)
* Creates new environment variables (replacing existing AWS_SES variables)
* Optionally allows more advanced setups using config files
* Update relay hosts during change detection (#922)
* Add helper scripts for adding relay hosts and per-domain auth
* Allow the possibility to deliver some mail directly
* adding a domain with no destination will exclude it from the
relayhost_map and so Postfix will attempt to deliver the mail directly
* tests for setup.sh script
* tests for relay host configuration
* these tests cover the code in `start-mailserver.sh` dealing with both
the env vars and the configuration files
* Added dependencies, binary, startup configuration
* Added env variable to dist files/readme
* send summary after each logrotate, added env variable for mail/logrotate interval
* remove mail.log from rsyslogs logrotate
* rotate mail.log when no email is set
* Added documentation for POSTFIX_LOGROTATE_INTERVAL
* Removed interval option, since its not being tested for.
* changed test to force logrotate to rotate fixed logrotate config
* readded setup_environment, made logrotate_setup being called everytime
* changed documentation for new variable names - again
* Did Documentation, added a default recipient, added test for default config.
* layout fix
* changed variable names apposite the documentation
* update postmaster_address in dovecot config according to POSTMASTER_ADDRESS env var
* tests: add another test for postmaster_address with default settings
* Introduced Postscreen
cheaper, earlier and simpler blocking of zombies/spambots.
From http://postfix.cs.utah.edu/POSTSCREEN_README.html :
As a first layer, postscreen(8) blocks connections from zombies and other spambots that are responsible for about 90% of all spam. It is implemented as a single process to make this defense as cheap as possible.
Things we need to consider:
- Do we need a whitelist/backlist file? (http://postfix.cs.utah.edu/postconf.5.html#postscreen_access_list)
- Via introducing an optional config/postfix-access.cidr
- The only permanent whitelisting I could imagine are monitoring services(which might (still?) behave weird/hastely) or blacklisting backup servers(since no traffic should be coming from them anyway)
- Do we need deep inspections? They are desireable, but these tests are expensive: a good client must disconnect after it passes the test, before it can talk to a real Postfix SMTP server. Considered tests are:
- postscreen_bare_newline_enable (http://postfix.cs.utah.edu/postconf.5.html#postscreen_bare_newline_action)
- postscreen_non_smtp_command_enable (http://postfix.cs.utah.edu/postconf.5.html#postscreen_non_smtp_command_action)
- postscreen_pipelining_enable (http://postfix.cs.utah.edu/postconf.5.html#postscreen_pipelining_action)
- Do we need to make the blacklisting via dnsblocking configurable? It's currently set and weighted as follows, where a score of 3 results in blocking, a score of -1 results in whitelisting:
(*: adds the specified weight to the SMTP client's DNSBL score. Specify a negative number for whitelisting.)
(http://postfix.cs.utah.edu/postconf.5.html#postscreen_dnsbl_sites)
- zen.spamhaus.org*3
- bl.mailspike.net
- b.barracudacentral.org*2
- bl.spameatingmonkey.net
- bl.spamcop.net
- dnsbl.sorbs.net
- psbl.surriel.com
- list.dnswl.org=127.0.[0..255].0*-2
- list.dnswl.org=127.0.[0..255].1*-3
- list.dnswl.org=127.0.[0..255].[2..3]*-4
- What to do when blacklisting? I currently set it to drop. We could
- 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.
- 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.
In the end I think we could drop postgrey support. Postscreen replaces postgrey in its entirety, while being more selective and not delaying mail. Especially if we consider using the deep inspection options of postscreen.
Hope that wasn't too much to read! ;)
* main.cf got misformatted..
Don't know how, should be ok now.
* fixed malformatted main.cf & repaired master.cf
* reenabled rbl stuff.. It's cached, therefore doesn't hurt
* fixed tests
* added tests, repaired tests, added info, introduced new Variable POSTSCREEN_ACTION, fixes
* fail2ban handling integrated in setup.sh
- calling \"./setup debug fail2ban\" lists all iptable chains whith blocked IPs (like: Banned in dovecot: 91.200.12.164
Banned in postfix-sasl: 91.200.12.164)
- calling \"./setup debug fail2ban unban xxx.xxx.xxx.xxx [yyy.yyy.yyy.yyy ...]\" unbans/removes those IPs from all jails.
- calling \"./setup debug fail2ban unban\" (without an IP) gives an descriptive error: (You need to specify an IP address. Run "./setup.sh debug fail2ban" to get a list of banned IP addresses.)
* disable_vrfy_command: (#798)
Prevents Spammers from collecting existing mail-addresses by probing the mailserver for them.
* Added support for Dovecot and Postfix LDAP TLS (#800)
* Allow setup of LDAP STARTTLS for Dovecot and Postfix
* Added tests for TLS config override
* Add missing Postfix TLS options
* Added missing new line at the end of the file
* Added STARTTLS tests for Postfix config
* tests added
and made the script output look more shiny.
* setup.sh enhancements
* Allow setup of LDAP STARTTLS for Dovecot and Postfix
* Added tests for TLS config override
* Add missing Postfix TLS options
* Added missing new line at the end of the file
* Added STARTTLS tests for Postfix config
* Switch to stretch-slim as base image.
- first step correct the testdata, as newer packages are more strict
about the mail-structure.
* Switch to stretch-slim: correcting the test-environment and the build
- add missing build-step to make
- clean the userdb aswell
- use timeout of netcat, as postgrey would not close the connection
- there is 2 extra mail-logs -> assert_output 5
- cosmetic: use "" instead of ''
* Switch to stretch-slim:
new image:
- smaller size
- 0 CVEs compared to 11 CVEs in ubuntu 16.04 Image
better backport situation
- postfix 3.1.6 vs 3.1.0
- fail2ban 0.9.6 vs 0.9.3
...
changes needed because of stretch-slim:
- add missing gnupg and iproute2 package
- remove non-free rar, unrar-free should do
- rsyslog does not add syslog user and has different conf-structure
- pyzor command discover was deprecated and is missing in the new
stretch package
- dovecot does not know SSLv2 anymore. removed because of warnings in
log
- iptables does not know imap3, IMAP working group chose imap2 in favor
of imap3
* Switch to debian stretch slim:
SSLv2 seems to be a not known protocol anymore - good!
* switch to debian stretch slim:
make this test more stable. there might be more than only one mail.log
(mail.info, mail.warn, ...)
* switch to debian stretc slim:
new openssl 1.1.0 needs stronger ciphers, removed some weekers ones.
Please, look through the new list of cipher! this needs to be done in
another commit for all other SSL/TLS-Endpoints aswell.
* Switch to debian stretch slim:
let our server pre-empt the cipher list.
Did a read through, wwwDOTpostfixDOTorg/FORWARD_SECRECY_READMEDOThtml
and
wwwDOTpostfixDOTorg/TLS_READMEDOThtml
* Switch to debian stretch slim: lets give this openssl-based test a new and independent but identical container. many other test on the main 'mail' container might interfere here.
* Switch to debian stretch slim: remove unused lines
This command can be used for generating DKIM key for a domain,
which is not included in any configuration files. For example,
when using SQL database for transport maps.
* installed supervisor. Still need to set tasks to run in foreground.
* setting programs to run in foreground
* seems to work now
* cleanup
* final fixes
* tests
* show startup output on stdout
* set Dovecot config files before starting it
* make all processes log to console
* Use the supervisor as the main process. The start-mailserver is started
from the supervisord and then this process triggers others.
Defined some default variable in the Dockerfile. In order for
supervisored to build the command lines the ENV variable need to be set.
Therefore the defaults are defined.
Some processes are not single processes like postfix and fail2ban and
they have a wrapper. The wrapper takes care of proper shutdown and checking
if the process is running or not. Supervisored will restart the wrapping
script if the process is gone.
Increased some delays between tests because sometimes they where to short
for all containers to be running.
* Remove obsolete comments, reset timeout value to old one, added new lines
* Add more time for analyzing the emails.
Sometimes it fails the tests and gives a wrong state about
the test. During testing 40 seconds was the safe value.
* Fix Dovecot Ldap Problems
* Fix typo within DEFAULT_VARS Definitions
* Fix wrong ldap hosts value within the bats test
* Fix override_config for strings containing &
* Fix erroneous removal of an conditional within the postfix override function
* Renamed Test 129, to be clear that this belongs to ldap
* Fix mail_with_ldap setting dn pass explicit
* Add 3 env variables for ldap: LDAP_QUERY_FILTER_{USER,GROUP,ALIAS}
* Update README.md
* Environment variable for spam subject tag
* Add SA_SPAM_SUBJECT to readme
* Add integration tests for spam subject tag
* Fix overwrite environment variable in config file
* First pass at adding support for pipe and filter in Sieve, excluding unit tests.
* Reduce insight into copied scripts
* Added test
* Adjustments related to switch to 16.04
* Fix #526: fatal: no SASL authentication mechanisms
When using the container with SMTP_ONLY = 1, then the container fails
on ehlo because there is no valid sasl authentication mechanism
available. This happens because sasl has been enabled within
postfix/main.cf per default but sasl is not configured.
To fix this _setup_postfix_sasl does not depend anymore on
ENABLE_SASLAUTHD and will check in it's logic, whether to enable sasl
or not within postfix/main.cf.

* Fix test
* Add method overwrite_config()
This method takes 2 arguments:
1.) Environment Variable Prefix
2.) String of files separated by whitespace
e.g.
export LDAP_SEARCH_BASE=dc=domain,dc=loc
export LDAP_BIND_PW=test
overwrite_config "LDAP_" "/etc/postfix/ldap-users.cf
/etc/postfix/ldap-groups.cf"
Logic:
+ all env vars will be search for vars with the prefix LDAP_
+ afterwards they will be dissembled in key value pairs
LDAP_BIND_PW=test --> bind_pw test
+ the key and value will be substituted within the provided files
via sed
* Fix #503 added logic for custom configs provided at container
provisioning within /tmp/docker-mailserver
* Add additional unit tests for postfix ldap integration
* check custom configs copied
* check environment variables substituted
* Fix quoting problems in tests.bats
* Fix missing brackets in function _fix_var_amavis_permissions()
* Fix typo in _setup_ldap
* Fix notify in overwrite_config
* Fix typo
* Fix added dovecot ldap config provisioning again and Add notify for tasks
* Fixed wrong mail headers when using OVERRIDE_HOSTNAME by setting the the hostname explicitly
* Added tests and fixed hostname in dovecot conf
* Added missing tests
* Improved function naming and task notification message
* Added `bats-assert` for more detailed error, very useful locally and on Travis
* Moved `bats` to git submodule
Example:
```
not ok 52 checking opendkim: generator creates keys, tables and TrustedHosts
# (from function `assert_output' in file test/test_helper/bats-assert/src/assert.bash, line 239,
# in test file test/tests.bats, line 368)
# `assert_output 2' failed
#
# -- output differs --
# expected : 2
# actual : 4
# --
#
```
* Add #394: Postfix Virtual Transport
This makes it possible to specify a lmtp config file, by providing
POSTFIX_DAGENT.
Update - Readme with informations about #394
* Add Variable ENABLE_POSTFIX_VIRTUAL_TRANSPORT (task)
* Add Variable POSTFIX_DAGENT (section)
Added Unit tests for virtual transport
* Fix syntax error in test/tests.bats
* Fix Unit Test
* Add some checks for user name matching in mail user scripts
* Fix user matching problems in mail user scripts
** fix matching problems at several places:
"delmailuser a@example.com" deletes also user "aa@example.com"
"delmailuser a@sub.example.com" deletes also user "a@sub-example.com"
** similar problems when inserting
** refactor and clean up
* Removed DISABLE_AMAVIS
* Renamed DISABLE_* to ENABLE_* with 0 as default value. (this must be explicit)
* Added missing tests for ENABLE_*
* Improved readme and docker-compose example
Should fix #256 and #386
* Improve and extend setup.sh
Add subcommands 'debug show-mail-logs', 'inspect', 'login'. Add option
'-c' to specify the name of the running container. Add option '-i' to
specify the image name.
* Add tests for setup.sh
The letsencrypt-auto client creates cert.pem, chain.pem, fullchain.pem, and
privkey.pem in its default settings. The simp_le client creates cert.pem,
fullchain.pem, and key.pem in its default settings.
A check for either privkey.pem or key.pem was added.
The chain.pem file was only used by the letsencrypt code for the creation of
combined.pem, which is not used by either postfix or dovecot.
The code to create a combined.pem file for letsencrypt was removed, as was the
corresponding test.
This commit adds a script nammed 'listmailuser'. './setup.sh' uses this
this script for its subcommand './setup.sh email list'. A test have
been added too.
* Wrote functional tests for desired behavior.
Redoing the pull request, starting from current master.
The tests now fail where expected.
* Updated commands to handle missing files better.
The functional tests now pass.
* Adding the PERMIT_DOCKER option
See README.md for more informations
* Adding some test for PERMIT_DOCKER option
* Fix test cases
* Opendkim and Openmarc configuration
Fix docker network range
Adding opendkim and openmarc configuration
* Adding some options for tests
* Update log message
* Update tests
* Allow disabling amavis service
Setting the `DISABLE_AMAVIS=1` env var will skip the starting of the
amavis process.
* Enable option to not run spamassassin
Setting the `DISABLE_SPAMASSASSIN=1` env var will start this container
without spamassain.
* Allow starting of the container without clamav
Setting the `DISABLE_CLAMAV=1` env var will start this container without
starting clamav.
The dovecot-sieve plugin is installed and configured to apply sieve
as soon as a .dovecot.sieve file is encountered in the virtual user's
home directory (that is /var/mail/${domain}/${username}/.dovecot.sieve).
Transport has been changed in the postfix configuration to use
Dovecot LDA (see http://wiki.dovecot.org/LDA/Postfix) to actually
enable sieve filtering.
Tests have been added.
(encrypted passwords).
Modified integration tests to adapt to dovecot.
Need to be worked out:
- user accounts checks: dir layout under dovecot probably include dynamic filenames.
How can we handle that ?
- fail2ban container cannot ban via iptables if we do not run it with special
privileges.
/var/log/mail directory.
Fail2ban jails and logrotate config files have been updated accordingly.
Integration tests have been extended to include a check of the new path.
