Re: How to set a part type for a add_body_part
Hi Theo,
Hrm. FYI, there are assumptions made that the internal message structure is
from the original message. So while I don't think things will break, some
rules may trigger inappropriately if you blow their mind.
I'll try for a while.
$part_array-[0]=3D--$boundary;
$part_array-[1]=3DContent-Type: image/tiff;;
$part_array-[2]=3DContent-Transfer-Encoding: Base64;
$part_array-[3]=3D;
Part data doesn't have mime boundaries and headers. It's just the part
content. You would want to parse/shove this data into the object header.
OK, nor they are encoded anymore.
open(FILE, $dir/$tifffile) or die $!;
while (read(FILE, $buf, 60*57)) {
$part_array-[$pline++]=3DMIME::Base64::encode_base64($buf);
}
Don't you have this from the message tree already?
No, this is a new image, extracted from the PDF part attached to the
message.
$part_msg-header(content_type, image/tiff);
I think you'd want content-type.
Of course :(
push(@{$msg-{'parse_queue'}}, [ $part_msg, $boundary, $part_array, 1=
]);
$msg-add_body_part($part_msg);
This doesn't make sense. You either want to add the body part to
the correct part of the tree, or setup the parse queue
appropriately and let it do it.
This I borrowed from SpamAssassin code directly as there are very few
examples of add_body_part around. It's in Message.pm.
# we've created a new node object, so add it to the queue along with the
# text that belongs to that part, then add the new part to the current
# node to create the tree.
push(@{$self-{'parse_queue'}}, [ $part_msg, $p_boundary, $part_array, $su
bparse ]);
$msg-add_body_part($part_msg);
I could not find any proper way to associate the body of the part in
$part_array with the node defined in part_msg: there is the method
header to add /modify a header of a part, but no similar (documented)
method to add/modify the body of the part.
Best regards,
Olivier
Re: what does whitelist_from act on
K Anand wrote: I have whitelist_from [EMAIL PROTECTED] in my conf. As per the docs, they say that whitelist_from will act on Envelope-Sender Resent-Sender X-Envelope-From From In addition, the ``envelope sender'' data, taken from the SMTP envelope data where this is available, is looked up. See |envelope_sender_header|. So it should also, by default, match the Return-Path header. *HOWEVER* that assumes the header is present at the time of scanning. Normally this header is not present at the MTA layer. It's a delivery agent thing. Many MTA layer SA integration tools create a fake return-path header and then remove it. SimScan (which you appear to use) doesn't do this, at least, the last person who was asking about the same basic problem (although it was relating to SPF, it still was failing due to lack of envelope information at scan time). You might be able to use the same solution he did, which patches qmail to add the envelope-from information to your Received: headers. See also: http://wiki.apache.org/spamassassin/QmailSpfPatch
Multiple domains, only the first is tagged
I use Fedora Core 8, amavisd-new, clamav and spamassassin, all current releases. I have 3 domains (non commercial), only the first domain is tagged, the others not. Virus is checked for all domains. What can I try to fix this? I already googled and searched for it but did not found any working solution.

It works fine now, thanks!
Thanks a lot! I found that line on google before, only the person in that post had all the domains between the scare brackets []. After changing the line as in your example it works fine...

Would that be a better way to do it? It seems to work too.
$part_msg-{'type'}=image/tiff;
$part_msg-{'name'}=$tifffile;
$part_msg-header(content-type, image/tiff);
$part_msg-{'raw'}=$part_array;
$msg-add_body_part($part_msg);

FuzzyOcr: selecting what frame for animated GIFs
Hi, By default FuzzyOcr will analize only one frame from animated GIFs. If the animation goes one word by frame: Click, Here, Now, selecting only one frame will give no sensible result. It woul dbe better to concatenate all the frames into one single image and process that image. The following patch does that: http://fuzzyocr.own-hero.net/ticket/420 - if the loop is finite (or if there is no loop), only the last frame is analyzed; - if the loop is infinite but one frame is on display for a duration that is much longer than other frames, only that frame is analyzed. The exact definition of much longer is open to discussion, I choosed that the dominant frame should be there on more than 50% of teh total time of the animation, but one could choose that the dominant frame should be only x time the average duration of one frame. - else all the frames are constructed into a single image that is analyzed. Bests, Olivier
FuzzyOcr: Pushing OCR'ed text back to SA
Hi, This ticket in FuzzyOcr http://fuzzyocr.own-hero.net/ticket/15 is proposing to send the text resulting from from the OCR process back to SA for analysis. I fully second that idea but I am wondering *what* text to push back: depending on teh scanset being used the same image will decode as: [20834] dbg: FuzzyOcr: ocrdata=. Uíagra tl.7g [20834] dbg: FuzzyOcr: . Cíalís t2.6g [20834] dbg: FuzzyOcr: [20834] dbg: FuzzyOcr: =end [20834] dbg: FuzzyOcr: ocrdata==end [20834] dbg: FuzzyOcr: ocrdata=. Uíagra tl.7g [20834] dbg: FuzzyOcr: . Cíalís t2.6g [20834] dbg: FuzzyOcr: [20834] dbg: FuzzyOcr: =end [20834] dbg: FuzzyOcr: ocrdata=' Viagra tl.79 [20834] dbg: FuzzyOcr: ' CiaIis t2.69 [20834] dbg: FuzzyOcr: =end The last scanset is the one prefered by FuzzyOcr when we let it do the word analysis, but the first may even be enough for SA. So the question really is: when can we say that the OCR is giving clean enough results that could be used by SA? We should not give SA the result of all scansets, else that would artificially raise the spam score. On another hand, for a photgraphy, OCR text may look like the following this, this should never be pushed to SA, so how to decide? [19120] dbg: FuzzyOcr: ocrdata=. ._ . [19120] dbg: FuzzyOcr: _\ [19120] dbg: FuzzyOcr: | _ [19120] dbg: FuzzyOcr: _ | [19120] dbg: FuzzyOcr: [19120] dbg: FuzzyOcr: _? _4'| [19120] dbg: FuzzyOcr: , _ ,. . .

Force plugins order
Hello, Is there a way to force the order that SA will try the various plugins? Typically I would have: - a first plugin that analyzes PDF attachment, pushed the text part back as text (post_message_parse) and the images as new message parts (add_body_part); - a second plugin that does OCR of the images attachments and pushes the discovered text back as text (post_message_parse). Obviously the first plugin should come first as it may discover images that will be OCRed by the second plugin. How to force the order of the plugins? Best regards, Olivier
