Now this is a bit tricky, but works great if you can decide which Top Level Domains or TLDs you want to receive mail We are getting so much spam from countries we never receive useful mail, I've been experimenting with blocking entire TLDs using sendmail access_db as an antispam technique.
Here is my current list, working great... yes I might miss a good one, but it blocks SO MUCH junk :
Combining this TLD blocking with Procmail charset filters has cut my spam down to fraction of what it was.......
Hi,

Hello,
So here's what I am trying to accomplish. We have a sendmail server and we are trying to stop backscattering. One idea that we came up with to prevent this is to utilize sendmail's access database.
Basically we'd have the first line bounce all mail coming in to our mail server to users... (9 Replies)

mail::spamassassin::permsgstatus
Mail::SpamAssassin::PerMsgStatus(3) User Contributed Perl Documentation Mail::SpamAssassin::PerMsgStatus(3)NAME
Mail::SpamAssassin::PerMsgStatus - per-message status (spam or not-spam)
SYNOPSIS
my $spamtest = new Mail::SpamAssassin ({
'rules_filename' => '/etc/spamassassin.rules',
'userprefs_filename' => $ENV{HOME}.'/.spamassassin.cf'
});
my $mail = Mail::SpamAssassin::NoMailAudit->new();
my $status = $spamtest->check ($mail);
if ($status->is_spam()) {
$status->rewrite_mail ();
$mail->accept("caught_spam");
}
...
DESCRIPTION
The Mail::SpamAssassin "check()" method returns an object of this class. This object encapsulates all the per-message state.
METHODS
$isspam = $status->is_spam ()
After a mail message has been checked, this method can be called. It will return 1 for mail determined likely to be spam, 0 if it does
not seem spam-like.
$list = $status->get_names_of_tests_hit ()
After a mail message has been checked, this method can be called. It will return a comma-separated string, listing all the symbolic
test names of the tests which were trigged by the mail.
$num = $status->get_hits ()
After a mail message has been checked, this method can be called. It will return the number of hits this message incurred.
$num = $status->get_required_hits ()
After a mail message has been checked, this method can be called. It will return the number of hits required for a mail to be consid-
ered spam.
$report = $status->get_report ()
Deliver a "spam report" on the checked mail message. This contains details of how many spam detection rules it triggered.
The report is returned as a multi-line string, with the lines separated by "
" characters.
$status->rewrite_mail ()
Rewrite the mail message. This will add headers, and possibly body text, to reflect its spam or not-spam status.
The modifications made are as follows:
Subject: header for spam mails
The string "*****SPAM*****" (changeable with "subject_tag" config option) is prepended to the subject, unless the "rewrite_subject
0" configuration option is given.
X-Spam-Status: header for spam mails
A string, "Yes, hits=nn required=nn tests=..." is set in this header to reflect the filter status. The keys in this string are as
follows:
X-Spam-Report: header for spam mails
The SpamAssassin report is added to the mail header if the "report_header 1" configuration option is given.
hits=nn The number of hits the message triggered.
required=nn The threshold at which a mail is marked as spam.
tests=... The symbolic names of tests which were triggered.
X-Spam-Flag: header for spam mails
Set to "YES".
Content-Type: header for spam mails
Set to "text/plain", in order to defang HTML mail or other active content that could "call back" to the spammer.
X-Spam-Checker-Version: header for spam mails
Set to the version number of the SpamAssassin checker which tested the mail.
spam mail body text
The SpamAssassin report is added to top of the mail message body, unless the "report_header 1" configuration option is given.
X-Spam-Status: header for non-spam mails
A string, "No, hits=nn required=nn tests=..." is set in this header to reflect the filter status. The keys in this string are the
same as for spam mails (see above).
$messagestring = $status->get_full_message_as_text ()
Returns the mail message as a string, including headers and raw body text.
If the message has been rewritten using "rewrite_mail()", these changes will be reflected in the string.
Note: this is simply a helper method which calls methods on the mail message object. It is provided because Mail::Audit uses an
unusual (ie. not quite intuitive) interface to do this, and it has been a common stumbling block for authors of scripts which use Spa-
mAssassin.
$status->finish ()
Indicate that this $status object is finished with, and can be destroyed.
If you are using SpamAssassin in a persistent environment, or checking many mail messages from one Mail::SpamAssassin factory, this
method should be called to ensure Perl's garbage collection will clean up old status objects.
