Include /etc/dspam/dspam.d/
2. 在/etc/postfix/master.cf最后添加

-o smtpd_authorized_xforward_hosts=127.0.0.0/8
-o content_filter=

dspam-retrain unix - n n - 10 pipe
flags=Ru user=dspam argv=/etc/dspam/dspam-retrain $nexthop $sender $recipient
3. 在/etc/postfix/main.cf最后添加
smtpd_client_restrictions =
check_client_access pcre:/etc/postfix/dspam_filter_access
permit_auth_destination
4. 创建/etc/postfix/transport，内容如下：
spam@pymain.pymain.net dspam-retrain:spam
ham@pymain.pymain.net dspam-retrain:innocent
5. 创建/etc/postfix/dspam_filter_access，内容如下：
/./ FILTER lmtp:[127.0.0.1]:11124
6. 创建/etc/dspam/dspam-retrain，内容如下：
# Get arguments
$class = $ARGV[0] || die; shift;
$sender = $ARGV[0] || die; shift;
$recip = $ARGV[0] || die; shift;
if ($recip =~ /^(spam|ham)-(\w+)@/) {
# username is part of the recipient
$user = $2;
} elsif ($sender =~ /^(\w+)@/) {
# username is in the sender
$user = $1;
} else {
print "Can‘t determine user\n";
exit 75; # EX_TEMPFAIL
}
# Pull out DSPAM signatures and send them to the dspam program
while (<>) {
if ((! $subj) && (/^Subject: /)) {
$subj = $_;
} elsif (/(!DSPAM:[a-f0-9]+!)/) {
open(F, "|/usr/bin/dspam --source=error --class=$class --user $user");
print F "$subj\n$1\n";
close(F);
} elsif (/(X-DSPAM-Signature: [a-f0-9]+)/) {
open(F, "|/usr/bin/dspam --source=error --class=$class --user $user");
print F "$subj\n$1\n";
close(F);
}
}
7. 修改/etc/dspam/dspam-retrain权限
#chmod +x /etc/dspam/dspam-retrain
. TAG: postfix dspam 配置方法
