Hi,
I have it working now, but an extra issue came up.
We found out that more mta's put the "X-Spam-Flag" in their header, so i
want to use the amavisd-custom.conf , only if the message comes from our
isp.
I have found a solution, I use :
my($subj) = $msginfo->get_header_field_body('X-Spam-Flag',0);
my($from) = $msginfo->get_header_field_body('Received',0);
and then
if ($subj =~ /^[ \t]YES/) {
if ($from =~ /ourisp.com/) {
This works great, but i was wondering, is it possible to create an if
statement, or something that looks like a policy bank in amavisd.conf,
like the following :
@myisp = qw ( 10.20.0.0/16 64.20.10.0/16 );
$policy_bank{'MYISP'} = {
include_config_files('/etc/amavisd-custom.conf');
};
Maybe a policy bank is not the answer, but something like that.
So if an IP number from our isp sends the message to our MTA, only then
I do the quarantaine trick.
Is something like this possible, or should i keep using the
amavisd-custom.conf the way i use it know.
Greetings.... Richard
