In a nutshell: use the policy access server for basic rules and actions at<br> &gt; \
first, and only if the ruleset gets<br> &gt; complicated with content filtering, \
return a &quot;FILTER&quot; action in the server,<br> &gt; and continue filtering<br>
&gt; with a milter? Probably i will have then to double check the matching<br>
&gt; rules, which is not nice. Or is it<br>
&gt; possible to pass, for example an identifier (matched rule uuid) to the<br>
&gt; milter?<br>
<br>
A policy server can return a PREPEND action to set a message header<br>
that can be examined down-stream. Returning a FILTER action is also<br>
possible, but you can&#39;t do that in the same action as PREPEND. Maybe<br>
you can do it as an end-of-data action.<br>
<br>
Of course anyone else can also PREPEND headers before sending you<br>
email, so be careful with that.<br>
