====== ASSP ======

''ASSP'' is a mail proxy aiming towards fighting spam. This page covers how I
installed ''ASSP'' onto my system and set it up.

My main interest is to have SRS/SPF running, sadly [[system:mta:postfix]] still has no
support for that.


===== Installation And Initial Setup =====

After installing ''ASSP'' initial configuration can be done by starting it,
and browsing to port 55555 on the machine running it. As my server has
iptables running, I achieved accessibility using an SSH tunnel:
  % ssh -L 55555:localhost:55555 my.server.tld

**BEWARE:** the admin interface heavily uses javascript, without it
configuration is a PITA. So if there is a very long page with a non-working
navigation bar, maybe Firefox's NoScript plugin is active.

===== Integration with Postfix =====

First, a new service has to be registered inside ///etc/services// for an
internal-only running MTA. My //services// file already included an entry for
"any private mail system" on port 24, just had to uncomment it. This is the
port postfix will listen on, being fed with mails from ''ASSP'' which is
designed for being the entry point of mail processing and therefore listening
on port 25 of the external IP.

Next step is to change Postfix's listen port, which is done inside
//master.cf//:
<file>
smtp      inet  n       -       n       -       -       smtpd
</file>
has to be changed into:
<file>
private   inet  n       -       n       -       -       smtpd
</file>
''private'' has to match the name of the newly created service in
///etc/services//.
