    Hello,

    I can not get amavis + spamassassin to work. Using Postfix and Dovecot. Some headers in mails are missing, I have:
    X-Virus-Scanned: Debian amavisd-new at mail.mydomain.com
    but no "X-Spam-Checker-Version", "X-Spam-Level", "X-Spam-Status".
    I also mis "X-Virus-Status"

    Postfix master.cf have the following at the bottom:
    Code:
    amavis unix - - - - 2 smtp
            -o smtp_data_done_timeout=1200
            -o smtp_send_xforward_command=yes
    
    127.0.0.1:10025 inet n - - - - smtpd
            -o content_filter=
            -o local_recipient_maps=
            -o relay_recipient_maps=
            -o smtpd_restriction_classes=
            -o smtpd_client_restrictions=
            -o smtpd_helo_restrictions=
            -o smtpd_sender_restrictions=
            -o smtpd_recipient_restrictions=permit_mynetworks,reject
            -o mynetworks=127.0.0.0/8
            -o strict_rfc821_envelopes=yes
            -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks
    
    # Dovecot LDA
    dovecot   unix  -       n       n       -       -       pipe
      flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -d ${recipient}
    
    and main.cf
    Code:
    content_filter = amavis:[127.0.0.1]:10024
    receive_override_options = no_address_mappings
    
    The file /etc/amavis/conf.d/15-content_filter_mode looks:
    Code:
    use strict;
    
    # You can modify this file to re-enable SPAM checking through spamassassin
    # and to re-enable antivirus checking.
    
    #
    # Default antivirus checking mode
    # Uncomment the two lines below to enable it back
    #
    
    @bypass_virus_checks_maps = (
       \%bypass_virus_checks, \@bypass_virus_checks_acl, \$bypass_virus_checks_re);
    
    
    #
    # Default SPAM checking mode
    # Uncomment the two lines below to enable it back
    #
    
    @bypass_spam_checks_maps = (
       \%bypass_spam_checks, \@bypass_spam_checks_acl, \$bypass_spam_checks_re);
    
    1;  # insure a defined return
    
    and the file: vi /etc/amavis/conf.d/20-debian_defaults

    Code:
    use strict;
    
    $QUARANTINEDIR = "$MYHOME/virusmails";
    
    $log_recip_templ = undef;    # disable by-recipient level-0 log entries
    $DO_SYSLOG = 1;              # log via syslogd (preferred)
    $syslog_ident = 'amavis';    # syslog ident tag, prepended to all messages
    $syslog_facility = 'mail';
    $syslog_priority = 'debug';  # switch to info to drop debug output, etc
    
    $enable_db = 1;              # enable use of BerkeleyDB/libdb (SNMP and nanny)
    $enable_global_cache = 1;    # enable use of libdb-based cache if $enable_db=1
    
    $inet_socket_port = 10024;   # default listenting socket
    
    $sa_spam_subject_tag = '***SPAM*** ';
    $sa_tag_level_deflt  = 2.0;  # add spam info headers if at, or above that level
    $sa_tag2_level_deflt = 6.31; # add 'spam detected' headers at that level
    $sa_kill_level_deflt = 6.31; # triggers spam evasive actions
    $sa_dsn_cutoff_level = 10;   # spam level beyond which a DSN is not sent
    
    $sa_mail_body_size_limit = 200*1024; # don't waste time on SA if mail is larger

    $MAXFILES = 1500;
    $MIN_EXPANSION_QUOTA =      100*1024;  # bytes

    # You should:
    #   Use D_DISCARD to discard data (viruses)
    #   Use D_BOUNCE to generate local bounces by amavisd-new
    #   Use D_REJECT to generate local or remote bounces by the calling MTA
    #   Use D_PASS to deliver the message
    #
    # Whatever you do, *NEVER* use D_REJECT if you have other MTAs *forwarding*
    # mail to your account.  Use D_BOUNCE instead, otherwise you are delegating
    # the bounce work to your friendly forwarders, which might not like it at all.
    #
    # On dual-MTA setups, one can often D_REJECT, as this just makes your own
    # MTA generate the bounce message.  Test it first.
    #
    # Bouncing viruses is stupid, always discard them after you are sure the AV
    # is working correctly.  Bouncing real SPAM is also useless, if you cannot
    # D_REJECT it (and don't D_REJECT mail coming from your forwarders!).
    
    $final_virus_destiny      = D_DISCARD;  # (data not lost, see virus quarantine)
    $final_banned_destiny     = D_BOUNCE;   # D_REJECT when front-end MTA
    $final_spam_destiny       = D_BOUNCE;
    
    Any idea what's wrong??

    Can you restart amavisd and take a look at the mail log? amavisd logs which modules it loads; is SpamAssassin listed there? Any errors in the log?

    Below is the output from mail.log which shows spamassassin. I have also changed the parameter for "$sa_tag_level_deflt" to -1000 to always add headers (in /etc/amavis/conf.d/20-debian_defaults).

    Right after I restarted the amavisd I saw something interesting in mail.log:
    If I send a non-spam test message from my gmail account, the spam-related headers are not added. Why? It's seems to partly work but exactly as I want it.

    Is there any good "send-test-spam-online-service" that are reliable?

    I think I found something...

    From http://workaround.org/articles/ispmail-etch/#step-10-amavis-filtering-spam-and-viruses I found the quote below and added the similar in my config /etc/amavis/conf.d/50-user

    so it looks like:
    Code:
    $pax='pax';
    [I][B]
    @lookup_sql_dsn = (
        ['DBI:mysql:database=mail;host=127.0.0.1;port=3306',
         'mailuser',
         'mailuserpassword']);
    
    $sql_select_policy = 'SELECT domain FROM domain WHERE CONCAT("@",domain) IN (%k)';[/B][/I]
    
    What's the purpose of "pax"?

    It seems that the added lines make things to work and headers contains:
    Code:
    X-Virus-Scanned: Debian amavisd-new at mail.jarkeborn.se
    X-Spam-Score: 1.178
    X-Spam-Level: *

    I did the howto forge tutor "postfix and amavis-new for etch with spamassassassing"

    I tried the following sql query.

    @lookup_sql_dsn = (
    ['DBI:mysql:database=mail;host=127.0.0.1;port=3306',
    'mail_admin',
    'mail_admin_password']);

    $sql_select_policy = 'SELECT domain FROM domains WHERE CONCAT("@",domain) IN (%k)';

    I receive emails, now with spam scan into the haeder! :D

    X-Spam-Score: 0.963
