The message size limit was reduced in c8728eab from the postfix
default [1] of 10,240,000B = 10,000kiB = ~10MiB to only
1,048,576B = 1MiB. And the documentation claims that this would be 10MiB
instead of 1MiB.
Restore the old behaviour as default and fix the documentation as well.

* 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.
* 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
* remove two ciphers according to https://www.htbridge.com/ssl/ (NIST, HIPAA)
* added a switch via an environment variable to choose between modern and intermediate ciphers
* 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
* 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
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.
* 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

* Add Variable POSTFIX_DAGENT (section)
Added Unit tests for virtual transport
* Fix syntax error in test/tests.bats
* Fix Unit Test
* 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

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
One example was missing a useful line, which was present in the wiki's example and without which the example does not run.
A typographical error was found in a file.
