Re: Thunderbird Forwarding Spam
I edited the script to be able to run it from command line, it parses every
file under $dirname variable
and save the results (tripped emails) under $path.
I am not a Perl Coder (But a Java One ;) ) so comments are welcome. I made
it available here:
#!/usr/bin/perl
#
my $path = Spam/;
use Mail::SpamAssassin::Message;
use Data::UUID;
my $dirname = MailsSpamToProcess/;
opendir(DIR, $dirname) or die can't opendir $dirname: $!;
while (defined($file = readdir(DIR))) {
#print $dirname . $file;
open(INFO, $dirname . $file); # Open the file
@message = INFO; # Read it into an array
#print @message;
my $msg = Mail::SpamAssassin::Message-new(
{
'message' = [EMAIL PROTECTED],
}
) || die Message error?;
print @message;
foreach my $p ($msg-find_parts(qr/^message\b/i, 0)) {
eval {
#no warnings ;
my $type = $p-{'type'};
my $ug = new Data::UUID;
my $uuid1 = $ug-create_str();
my $attachname = $path . $uuid1 . .eml;
open OUT, , $attachname || die Can't write file
$attachname:$!;
binmode OUT;
print OUT $p-decode();
};
}
close(INFO);
}
closedir(DIR)
I have one more question, before i enable bayes filter on my site, what if
no bayes_path is specified on local.cf? Will it use the default path
(/root/.spamassassin/) ?
Thanks :) !
I haven't tested this script by running it manually and this script is
not written by me. But you can run it manually as it is a script it
can be run from the command line. I don't know about the parameters
may be you can pass a fake or unwanted email to this script.

hey,
There is a script which can do this. Create a user suppose
[EMAIL PROTECTED] and all the users will forward spam mails to
this address . Please note you need to choose forward as attachment
while forwarding the mail to this account ([EMAIL PROTECTED]
I am directly posting the mail from the person who helped me configuring this.
1) user forwards spam message AS ATTACHMENT to a pre-defined
email address
I tell my users to forward as attachment to [EMAIL PROTECTED]
2) postfix pipes emails to this address to the modified
script via local alias
I am also using virtual users. You have to make sure that postfix knows
how to handle local aliases. From my main.cf:
alias_maps = hash:/etc/aliases
...pointing to the local aliases file. Then within that file, set up a
local alias to pipe all input to the script. From my /etc/aliases:
spam-bayes: | /etc/scripts/strip_attached_messages.pl
... Be sure to run the command 'newaliases' after updating the aliases
file. Then you use virtual_alias_maps to set the
[EMAIL PROTECTED] address to forward to the alias you set up. I
use MySQL for my virtual_alias_maps, but if you use a file it would have
something like:
[EMAIL PROTECTED] spam-bayes
That will forward all emails sent to [EMAIL PROTECTED] to the
spam-bayes alias, which will in turn pipe them into your script.
3) the script strips out all attachments defined as content-type:
message/*
Cron isn't necessary if you have the alias set up.
5) a separate cron script then runs on a schedule to pipe all
messages in /tmp/spam into sa-learn and delete them afterwards
Need to setup the crontab to call this script
My cron script:
#!/bin/sh
/usr/local/bin/sa-learn --spam --username=vscan /tmp/spam/
/bin/rm /tmp/spam/*
--Username=vscan because I am using a single bayes database for all
mail, rather than individual bayes db's for each user. This method
wouldn't work for individual bayes setups. My crontab line:
53 1 * * * root
/etc/scripts/train-bayes.sh
... To run it once per day at 1:53 am. I get a nice email every morning
to root which says:
Learned tokens from 102 message(s) (102 message(s) examined)
The only thing to configure in the script is the path where you want the
attached messages stored until your sa-learn script runs. I save mine
to /tmp/spam/, and that's where the train-bayes.sh script looks for
them.
Hope this helps. It has been working very well for me so far.
the Script
_
#!/usr/bin/perl
use strict;
use warnings;
my @message = STDIN;
my $path = /tmp/spam/;
use Mail::SpamAssassin::Message;
use Data::UUID;
my $msg = Mail::SpamAssassin::Message-new(
{
'message' = [EMAIL PROTECTED],
}
) || die Message error?;
foreach my $p ($msg-find_parts(qr/^message\b/i, 0)) {
eval {
no warnings ;
my $type = $p-{'type'};
my $ug = new Data::UUID;
my $uuid1 = $ug-create_str();
my $attachname = $path . $uuid1 . .eml;
open OUT, , $attachname || die Can't write file
$attachname:$!;
binmode OUT;
print OUT $p-decode();
};
}

Re: Thunderbird Forwarding Spam
Hey, thanks for your help, because i see that it will take me some time to do
all that i'll ask you some preliminary questions:
1) Can i run the script by hand just for testing purposes? Do you know how
can i do this? Do i have to pass some parameters to the command line?
2)The script takes the message and leaves everything down Content-Type:
Message right?
3) Can i follow this rules on a production server? is it safe ?
Many Thanks for your help!
your Script:
_
#!/usr/bin/perl
use strict;
use warnings;
my @message = STDIN;
my $path = /tmp/spam/;

my $msg = Mail::SpamAssassin::Message-new(

May be yes. The script extracts the original mail from the forwarded
mail and then through sa-learn we make spamassassin learn it as spam.
3) Can i follow this rules on a production server? is it safe ?
People are using it on production server including me.
