André Stein a9c4bb3615 Adapted Postfix configuration to block typical spam sending 
mail servers using an enhanced client, sender and helo
restriction configuration.

The configuration has been adapted using this blog post:
https://www.webstershome.co.uk/2014/04/07/postfix-blocking-spam-enters-server/

Basically mail servers having invalid configuration (as e.g. sending
from and dynamic IP or a misconfigured hostname) will have their
mails rejected.

Additionnally three RBL servers are used to detect spam sending
IPs: dnsbl.sorbs.net, zen.spamhaus.org and bl.spamcop.net.

The results of a 12h test drive using a 100+ daily spam
mail account (SpamAssasin was always enabled, just counting
delivered mails to inbox not counting what SA detected):
- Before: 34 incoming mails
- Afer change: 6 incoming mails (82% reduction)

Fixes #161.

V2 CI-tests
 2016-04-17 22:41:31 +02:00
angus a6d666b450 Improvements on CI tests: now user account checks are working. 
Need to work on fail2ban tests.
 2016-04-17 20:10:09 +02:00
angus b35c79a8dd Adapted the user account setup for the test environment to the new v2 approach 
(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.

make build builds with cache 
As `make build-no-cache` was added, it seems appropriate that `make
build` should build with the cache, so I have removed the `--no-cache`
option.
