Postfix Backscatter

Hi,

My server is in the backscatterer.org database. It's a Debian Perfect setup installation with ISPConfig 2. I tried to read the Postfix Backscatter Howto, but it's not simple to understand as the configuration is not the same. In this howto, they speak about local_recipient_maps but ISPConfig uses virtual_maps. They also speak about unknown_local_recipient_reject_code = 550 wich should be the default in everything > postfix 2.4, as I use 2.7 this should not be the problem.

I don't see what could be the problem, does someone have a clue about what could be wrong?
Is there an easy Test I could do to test my server for Backscatter?

Thanks

 

Can you post your main.cf?

 

Thank's for your reply, here it is :

Code:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = delta.myhost.fr
alias_maps = hash:/etc/aliases hash:/var/lib/mailman/data/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
#mydestination = delta.myhost.fr, localhost.myhost.fr, localhost.localdomain, localhost
relayhost = 
mynetworks = 127.0.0.0/8
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
smtpd_sasl_local_domain = 
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom

virtual_maps = hash:/etc/postfix/virtusertable

mydestination = /etc/postfix/local-host-names
smtpd_sasl_authenticated_header = yes
relay_domains = lists.myhost.fr
transport_maps = hash:/etc/postfix/transport
mailman_destination_recipient_limit = 1

 

An option could be changing the "$final_spam_destiny" value from "D_BOUNCE" to "D_DISCARD" in /etc/amavis/conf.d/20-debian_defaults

Change: "$final_spam_destiny = D_BOUNCE;" to "$final_spam_destiny = D_DISCARD;"

Basicaly spam is now not bounced back, but deleted.

 

Thanks for your reply, but as far as I know ISPConfig 2 does not use amavis, or am I missing something?

 

Thanks Till, I didn't think about the autoresponder, but unfornatelly it's not the case, I'searched the db, and user_autoresponder is either set to 0 or NULL.

could the problem be that I switched to spamd?
