trying to score based on image name and image size
I notice there's a:
mx1:/usr/share/perl5/Mail/SpamAssassin/Plugin# ls -lah ImageInfo.pm
-rw-r--r-- 1 root root 11K Aug 8 2007 ImageInfo.pm
and within that there's two subs 'image_named' and 'image_size_exact'
mx1:/usr/share/perl5/Mail/SpamAssassin/Plugin# cat ImageInfo.pm |grep
image_named
$self->register_eval_rule ("image_named");
sub image_named {
mx1:/usr/share/perl5/Mail/SpamAssassin/Plugin# cat ImageInfo.pm |grep exact
$self->register_eval_rule ("image_size_exact");
sub image_size_exact {
mx1:/usr/share/perl5/Mail/SpamAssassin/Plugin#
I am trying the following rule and it is not scoring, what am i missing?:
(this rule is in my local.cf)
# rule to block annoying viagra spam with scraped text based off image size,
# name and having other rule hits
# 4/30/09 8:45AM
body __ZL_PNG_400_240 eval:image_size_exact('png',400,240)
body __ZL_CAM eval:image_named('/^DS[CL]\d{4}\.png$/')
meta ZL_VIAGRAIMG HTML_MESSAGE && __ZL_CAM && __ZL_PNG_400_240
describe ZL_VIAGRAIMG Includes 400x240 viagra png image
score ZL_VIAGRAIMG 1.00
any help is appreciate thanks

aha i fixed it with the following:
# rule to block annoying viagra spam with scraped text based off image size,
# name and having other rule hits
# 4/30/09 8:45AM
body __ZL_PNG_240_400 eval:image_size_exact('png',240,400)
body __ZL_CAM eval:image_name_regex('/^DS[CL]\d{4}\.png$/')
meta ZL_VIAGRAIMG (HTML_MESSAGE && __ZL_CAM && __ZL_PNG_240_400)
describe ZL_VIAGRAIMG Includes 240x400 viagra png image
score ZL_VIAGRAIMG 2.0
i also set in the v310.pre
loadplugin SareImageInfo SareImageInfo.pm
and I also changed the package line for the Sare ImageInfo plugin
(found here: http://www.rulesemporium.com/plugins.htm#imageinfo)
so it wouldnt conflict with the SA version of ImageInfo
:)
tests have it working !
2.0 ZL_VIAGRAIMG Includes 240x400 viagra png image
based on that exact image size, that reg_ex image name and it being an html

thanks for the reply:
from the spamassassin -D plugin --lint , i got:
[20759] dbg: plugin: loading Mail::SpamAssassin::Plugin::ImageInfo from @INC
running -D imageinfo against the msg i get:
mx1:~/spam# cat spam6 |spamassassin -D imageinfo
[21510] dbg: imageinfo: png image DSC5051.png is 240 x 400 pixels (96000
pixels sq.)
[21510] dbg: imageinfo: image name DSC5051.png found
[21510] dbg: imageinfo: adding 240x400 to dems_all
[21510] dbg: imageinfo: image ratio=0.0353333333333333, min=0.000 max=0.008
[21510] dbg: imageinfo: image ratio=0.0569270833333333, min=0.000 max=0.015
ahh it reads it as 240x400 and my rule has 400x240, i bet that's the issue.
let me retry the rule as 240x400

Re: trying to score based on image name and image size
Posted by Theo Van Dinter <fe...@apache.org>.
There could be various reasons ranging from "plugin isn't loaded"
(though you'd get an error w/ the rules then) to "image isn't exactly
that size", to "plugin can't determine width+height from image", to
...
Assuming the plugin is loaded ("spamassassin -D plugin --lint" would
tell you), and you've verified that the size is what you think it is
using some method ... For option 3, run the message through
"spamassassin -D imageinfo" and see what it spits out. If you don't
see something like:
imageinfo: png image FOO.PNG is 400 x 240 pixels (96000 pixels sq.)
Then it didn't figure out the height + width. If it does output that,
compare the height and width to what you expected.
