    Hi

    Im running ispconfig 3.0.16 and have found this info on spamcop :

    http://www.spamcop.net/fom-serve/cache/349.html

    I did also find it in an old post here, but there was not much documentation on how to do it from a to z.

    The above mentioned link talking about editing main.cf and show an example of it.

    My main.cf is as followed... (domain changed) :

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

    append_dot_mydomain = no

    smtpd_tls_cert_file = /etc/postfix/smtpd.cert
    smtpd_tls_key_file = /etc/postfix/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

    myhostname = jamesbond.com
    alias_maps = hash:/etc/aliases
    alias_database = hash:/etc/aliases
    myorigin = /etc/mailname
    mydestination = jamesbond.com, localhost, localhost.localdomain
    relayhost =
    mynetworks = 127.0.0.0/8 [::1]/128
    mailbox_size_limit = 0
    recipient_delimiter = +
    inet_interfaces = all
    virtual_alias_domains =
    virtual_alias_maps = proxy:mysql:/etc/postfix/mysql-virtual_forwardings.cf, mysql:/etc/postfix/mysql-virtual_email2email.cf
    virtual_mailbox_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf
    virtual_mailbox_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailboxes.cf
    virtual_mailbox_base = /var/vmail
    virtual_uid_maps = static:5000
    virtual_gid_maps = static:5000
    smtpd_sasl_auth_enable = yes
    broken_sasl_auth_clients = yes
    smtpd_sasl_authenticated_header = yes
    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination
    smtpd_tls_security_level = may
    transport_maps = proxy:mysql:/etc/postfix/mysql-virtual_transports.cf
    relay_domains = mysql:/etc/postfix/mysql-virtual_relaydomains.cf
    virtual_create_maildirsize = yes
    virtual_maildir_extended = yes
    virtual_mailbox_limit_maps = proxy:mysql:/etc/postfix/mysql-virtual_mailbox_limit_maps.cf
    virtual_mailbox_limit_override = yes
    virtual_maildir_limit_message = "The user you are trying to reach is over quota."
    virtual_overquota_bounce = yes
    proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $virtual_mailbox_limit_maps
    smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf
    smtpd_client_restrictions = check_client_access mysql:/etc/postfix/mysql-virtual_client.cf
    maildrop_destination_concurrency_limit = 1
    maildrop_destination_recipient_limit = 1
    virtual_transport = maildrop
    header_checks = regexp:/etc/postfix/header_checks
    mime_header_checks = regexp:/etc/postfix/mime_header_checks
    nested_header_checks = regexp:/etc/postfix/nested_header_checks
    body_checks = regexp:/etc/postfix/body_checks
    content_filter = amavis:[127.0.0.1]:10024
    receive_override_options = no_address_mappings
    smtp_sasl_auth_enable=no
    message_size_limit = 0
    readme_directory = /usr/share/doc/postfix
    html_directory = /usr/share/doc/postfix/html

    Here is a sample of one user's main.cf where the SCBL is used:

    smtpd_recipient_restrictions =

    reject_invalid_hostname,
    reject_non_fqdn_sender,
    reject_non_fqdn_recipient,
    reject_unknown_sender_domain,
    reject_unknown_recipient_domain,
    reject_unauth_pipelining,
    permit_mynetworks,
    reject_unauth_destination,
    reject_rbl_client bl.spamcop.net
    permit

    How and where do i provide the above mentioned corretions to get already known spam dropped, so i dont have to check it in the inbox of the user ?

    Can main.cf be edited like this :

    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination, reject_invalid_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_unauth_pipelining, reject_unauth_destination, reject_rbl_client bl.spamcop.net

    or does it need a permit in the end like this :

    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_recipient_access mysql:/etc/postfix/mysql-virtual_recipient.cf, reject_unauth_destination, reject_invalid_hostname, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_unauth_pipelining, reject_unauth_destination, reject_rbl_client bl.spamcop.net
    permit

    If this is ok, is it then ok just to restart postfix after teh configurations are made ?

    Does anyone know how much spam this will remove and not get to the inbox ?

    You need a permit at the end of the line, and you must restart Postfix.

    Besides spamcop I added some additional blacklisting as well;

    bl.spamcop.net,
    zen.spamhaus.org,
    db.wpbl.info,
    rhsbl.sorbs.net,

    Works great, allmost all spam is blocked now.
    I was using the same servers for the last few years in Kerio-Mailserver as well
