postfx submission uses wrong amavis policy bank

[Christian Scholz]

Hello together,

I've got a question about the postfix submission and the regular 
content_filter/smtpd_proxy_filter filter.
My postfix master.cf configuration looks like:

smtp      inet  n       -       -       -       10       smtpd
   -o receive_override_options=no_address_mappings
   -o smtpd_authorized_xforward_hosts=127.0.0.0/8
   -o smtpd_authorized_xclient_hosts=127.0.0.0/8
   -o smtpd_proxy_filter=127.0.0.1:10031

# Submission Port 587 mit DKIM Signierung
submission inet n       -       -       -       10       smtpd
   -o receive_override_options=no_address_mappings
   -o smtpd_tls_wrappermode=no
   -o smtpd_sasl_auth_enable=yes
   -o smtpd_client_restrictions=permit_sasl_authenticated,reject
   -o content_filter=smtp-amavis:[127.0.0.1]:10026
   -o syslog_name=postfix-submission
   -o smtpd_proxy_filter=

# SMTPS Port 465 mit DKIM SIgnierung
smtps     inet  n       -       -       -       10       smtpd
   -o receive_override_options=no_address_mappings
   -o smtpd_authorized_xforward_hosts=127.0.0.0/8
   -o smtpd_authorized_xclient_hosts=127.0.0.0/8
   -o smtpd_tls_wrappermode=yes
   -o smtpd_sasl_auth_enable=yes
   -o smtpd_client_restrictions=permit_sasl_authenticated,reject
   -o content_filter=smtp-amavis:[127.0.0.1]:10026
   -o syslog_name=postfix-smtps
   -o smtpd_proxy_filter=

So I expected that an email from the localhost send over the submission 
port will run trough the content filter sasl_bypass on port 10026. But 
amavis send the email trough port 10031 which is the prequeue_filter for 
the "normal" smtp daemon. Here is the log extraction:

Oct 18 18:09:48 mx02 postfix/smtpd[24105]: connect from 
localhost.localdomain[127.0.0.1]
Oct 18 18:09:48 mx02 postfix/smtpd[24105]: NOQUEUE: 
client=localhost.localdomain[127.0.0.1], sasl_method=LOGIN, 
sasl_username=sender at domain.com
Oct 18 18:09:48 mx02 amavis-mynet[21732]: (21732-04) ESMTP::10031 
/var/lib/amavis/tmp/amavis-20111018T175643-21732: <sender at domain.com> -> 
<recipient at domain2.com> Received: from mx02.domain2.com ([127.0.0.1]) by 
localhost (mx02.domain2.com [127.0.0.1]) (amavisd-new, port 10031) with 
ESMTP for <recipient at domain2.com>; Tue, 18 Oct 2011 18:09:48 +0200 
(CEST)
Oct 18 18:09:48 mx02 amavis-mynet[21732]: (21732-04) Checking: 
qWgpcJS5+Gxq prequeue_filter/MYNETS [127.0.0.1] <sender at domain.com> -> 
<recipient at domain2.com>

I'made sure the the only postition were I forward a message to port 
10031 will be at the smtpd_proxy_filter. So I can't find a mistake... is 
there something that I don't know about the amavs submission behavior. 
Are there overlapping configuration parameters?
