Alle,
We would like to filter all internal email so that it bypasses
SpamAssassin. We have set up per_client_filters using:
smtpd_client_restrictions =
check_client_access cidr:/etc/postfix/per_client_filter
== per_client_filter:
0.0.0.0/0 FILTER spamassassin:
10.0.0.0/8 FILTER dummy:
...
Note that order matters in a cidr: table. First match wins;
everything matches 0.0.0.0/0. Put the catchall last, more specific
entries earlier.

The spamassasin filter works fine, but how do we create a dummy
filter that just does a bypass of all the internal emails?
Why send them through a filter at all if you don't want them
filtered? Use DUNNO as the table result.
10.0.0.0/8 DUNNO
0.0.0.0/0 FILTER...
Noel,
So this will accomplish what we want?
10.0.0.0/0 DUNNO
0.0.0.0/0 FILTER spamassassin:
Maybe not exactly. We have a similar setup. The problem here is,
that mails handed out to spamassassin (in our case its amavisd-new)
is reinjected by amavisd-new to postfix via localhost:10025. All
mails bypassing amavisd-new must be "manually" reinjected to port
10025 to accomplish address rewriting etc. (all the stuff that is
done AFTER content filtering).
So your setup would look like this:
10.0.0.0/0 FILTER smtp:[127.0.0.1]:10025
0.0.0.0/0 FILTER spamassassin:

Stefan,
Except we aren't using amavis and spamassassin processes traffic on
our DMZ. Virus scanning is done on the interior mail servers with
amavisd-new and ClamAV:
[EMAIL PROTECTED]:/etc/postfix [1002/2]# grep spamassassin master.cf
smtp inet n - n - - smtpd -o
content_filter=spamassassin
spamassassin
unix - n n - - pipe
user=nobody argv=/usr/bin/spamc -e /usr/lib/sendmail -oi -f ${sender}
${recipient}
Best Regards,

The DUNNO solution described earlier will work for any setup
that doesn't use "content_filter = something" in main.cf or
the receiving smtpd listener.
So it should work fine for you.
