 Posted: Tue Mar 15, 2005 10:46 am Post subject: [solved] Amavisd-new not writing X-Spam-* but X-Virus Header |
 |
|
Hi there,
I have installed postfix, spamassassin, amavisd-new, clamav on my mailserver.
Everything is working well except for Spam-Scanning.
amavisd-new puts spam-messages into quarantine, but the messages passed to the recipient do not contain any X-Spam-Headers nor the changed ****SPAM**** subject.
Important entries from amavisd.conf
| Code: |
$final_spam_destiny = D_PASS; # (defaults to D_BOUNCE)
$remove_existing_spam_headers = 0; # leave existing X-Spam* headers alone
# (I also tried with the above line set to 1, but didn't change anything)
$sa_local_tests_only = 0; # (default: false)
$sa_mail_body_size_limit = 200*1024; # don't waste time on SA if mail is larger
$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 to
$sa_kill_level_deflt = $sa_tag2_level_deflt; # triggers spam evasive actions
$sa_dsn_cutoff_level = 10; # spam level beyond which a DSN is not sent,
|
I'm quite sure that the mail is scanned for spam, as they are correctly put into quarantine and as the logfile says "ANTI-SPAM code loaded" when restarting amavisd-new.
The mails are correctly passed to amavisd-new and back to postfix, as the "X-Virus-Scanned by amavisd-new at myhostname" is added to the mail, you fetch via pop from the server.
I looked at the mails in /var/amavis/quarantine/. They contain the X-Spam-Headers!
My postfix configs main.cf and master.cf are based on the following Howto:
http://www.gentoo.org/doc/en/mailfilter-guide.xml
If it helps, here the important parts of the master.cf:
| Code: |
smtp inet n - n - - smtpd -v
-o content_filter=smtp-amavis:[127.0.0.1]:10024
#
# amavisd-new
#
smtp-amavis unix - - n - 2 smtp
-o smtp_data_done_timeout=1200
-o disable_dns_lookups=yes
127.0.0.1:10025 inet n - n - - smtpd
-o local_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 strict_rfc821_envelopes=yes
|
Does anyone have an idea what I could have configured wrong?
Thanks,
Martin

I just got it to change the body of the message by setting $defang_spam = 1;
Thus the original message was attached and I got a message telling me that the original message was spam.
But the X-Spam-Headers don't appear.... 
Could it be a bug in spamassassin? |

By the looks of things amavisd-new isn't quarantining spam, as you have FINAL_SPAM_DESTINY = D_PASS.
Can you see the SA headers in every mail? Try changing $sa_tag_level_deflt = -999 to make sure they always should appear.
hth,
Casper. |

Hey Casper,
thanks for your hint.
I set $sa_tag_level_deflt = -999, but it didn't help.
I tried with one ham and one spam message. The ham message is passed with the hint "Passed CLEAN" und is not put into quarantine. The spam message (that GTUBE test-spam message) was put into quarantine and furthermore passed with the hint "Passed SPAM" in the logs.
There were no X-Spam-Headers in the passed messages, neither in the ham message nor in the spam message!
The message in quarantine contained the following X-Spam-Headers:
X-Spam-Status: Yes, hits=1001.356 tag=-999 tag2=6.31 kill=6.31 tests=AWL,
BLANK_LINES_70_80, DNS_FROM_RFC_ABUSE, GTUBE, RCVD_BY_IP
X-Spam-Level: ****************************************************************
But strangely the quarantine-message did not contain the X-Virus-Scanned header, but the passed messages contain it...
What is happening with my amavisd-new...? |

I got it....
The problem was the setting:
$mydomain = serverkompetenz.net
As I have a machine with multiple virtual hosts, I set this domainname to the domain of Strato, which is housing my server. They give you a hostname something.serverkompetenz.net when you order a rootserver there.
When I tried $mydomain = my-real-domain.net, the X-Spam-headers were correctly added to all emails at my-real-domain.net. But the problem is, that they are not added to emails at the other domains, I am hosting on my server!
What can I do now? Can $mydomain be an array of all domains, I am hosting, so that everyone can benefit from spam-checking?
I think this is very confusing, mainly because of the comments in the config-file:
| Code: | # $mydomain serves as a quick default for some other configuration settings.
# More refined control is available with each individual setting further down.
# $mydomain is never used directly by the program.
|
This made me think that $mydomain is not a very important setting... |

OK, I think I didn't read the comments in the config file carefully enough.
The @local_domains_maps is used for that purpose. So my problem is solved... |
