@@ -2,60 +2,33 @@ This is a very first implementation of Postfix content filtering.
A Postfix content filter receives unfiltered mail from Postfix and
either bounces the mail or re-injects filtered mail back into Postfix.
It involves an incompatible change to queue file formats. Older
Postfix versions will reject mail that needs to be content filtered,
and will move the queue file to the "corrupt" mail queue subdirectory.
This document describes two approaches to content filtering.
Simple content filtering example
================================
The first example is simpler to set up, but is also more resource
intensive. With the shell script as shown you will lose a factor
of four in Postfix performance for transit mail that arrives and
leaves via SMTP. You will lose another factor in transit performance
for each additional temporary file that is created and deleted in
the process of content filtering. The performance impact is less
for mail that is submitted or delivered locally, because such
deliveries are not as fast as SMTP transit mail.
The example assumes that only mail arriving via SMTP needs to be
content filtered.
The first example is simple to set up. It uses a shell script that
receives unfiltered mail from the Postfix pipe delivery agent, and
that feeds filtered mail back into the Postfix sendmail command.
Only mail arriving via SMTP will be content filtered.

1 - Create a dedicated local user account called "filter". The
user will never log in, and can be given a "*" password and
non-existent shell and home directory. This user handles all
potentially dangerous mail content - that is why it should be
a separate account.
2 - Create a directory /var/spool/filter that is accessible only
to the "filter" user. This is where the content filtering will
store its temporary files.
3 - Define a content filtering entry in the Postfix master file:

Turn on content filtering for mail arriving via SMTP only, by
appending "-o content_filter=filter:dummy" to the master.cf
entry that defines the Postfix SMTP server:
Once you're satisfied with the content filtering script:
1 - Create a dedicated local user account called "filter". This
user handles all potentially dangerous mail content - that is
why it should be a separate account. Do not use "nobody", and
most certainly do not use "root" or "postfix". The user will
never log in, and can be given a "*" password and non-existent
shell and home directory.
2 - Create a directory /var/spool/filter that is accessible only
to the "filter" user. This is where the content filtering script
is supposed to store its temporary files.
3 - Define the content filter in the Postfix master file:
/etc/postfix/master.cf:
filter unix - n n - - pipe
flags=Rq user=filter argv=/somewhere/filter -f ${sender} -- ${recipient}
To turn on content filtering for mail arriving via SMTP only, append
"-o content_filter=filter:" to the master.cf entry that defines
the Postfix SMTP server:
/etc/postfix/master.cf:
smtp inet ...stuff... smtpd
-o content_filter=filter:dummy
-o content_filter=filter:
The content_filter configuration parameter accepts the same
syntax as the right-hand side in a Postfix transport table.
Note the ":" at the end!! The content_filter configuration parameter
accepts the same syntax as the right-hand side in a Postfix transport
table. Execute "postfix reload" to complete the change.
To turn off content filtering, edit the master.cf file, remove the
"-o content_filter=filter:" text from the entry that defines the
Postfix SMTP server, and execute another "postfix reload".
With the shell script as shown above you will lose a factor of four
in Postfix performance for transit mail that arrives and leaves
via SMTP. You will lose another factor in transit performance for
each additional temporary file that is created and deleted in the
process of content filtering. The performance impact is less for
mail that is submitted or delivered locally, because such deliveries
are already slower than SMTP transit mail.

tried in the order as listed below:

lookup patterns are examined in the order as listed:
