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
* install dovecot from backports
* dovecot 2.2.33 has a slightly different TLS-configuration than 2.2.27
* want to have both images a the same time
* make use of the /etc/dovecot/ssl as mkcert.sh (2.2.33) is using that folder for certs.
* Enable user definable fetchmail poll times
* create new ENV variable FETCHMAIL_POLL in target/start-mailserver.sh
* change --daemon setting in supervisor-app.conf to use ENV var
* Put FETCHMAIL_POLL env variable in Dockerfile to handle case where
user does not specify it in their docker-compose.yml
* 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
Moved variable VIRUSMAILS_DELETE_DELAY to Dockerfile. This variable will be written to /etc/environment in the start
script to make it visible to cron. Also removed echo in cron job to prevent sending mail for each run.
* 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
Fix "/usr/local/bin/start-mailserver.sh: line 489: [: argument expected"
There are quotes missing around a shell variable. I added some more, too.
[ -z ] is okay, but [ a = b -a -z ] is not.
