Need to score .html attachments.
Problem:
Some of our customer send us Purchase Orders as .html attachments. I
have spamassassin .cf rule sets that assign a very negative score for
any text that looks like a purchase order but these .cf rules don't work
on mail with like:
=20
Your files are attached and ready to send with this message.
------_=_NextPart_001_01C4D623.84C0990B
Content-Type: text/html;
name="04 2625 0713 Joe Smo Svc Sta Area B, MagneTek.htm"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="04 2625 0713 Joe Smo Svc Sta Area B, MagneTek.htm"
Here is the spam score.
Spam Analysis Report (Score = 27.6):
2.3 MANGLED_BODY BODY: mangled body
2.3 MANGLED_FROM BODY: mangled from
2.3 MANGLED_PURCHS BODY: mangled purchase(s)
2.3 MANGLED_ACCNT BODY: mangled account(s)
2.3 MANGLED_WEIGHT BODY: mangled weight
2.3 MANGLED_OFF BODY: mangled off
2.3 MANGLED_TEXT BODY: mangled text
2.3 MANGLED_DELIVY BODY: mangled delivery
2.3 MANGLED_MEN BODY: mangled men
2.3 MANGLED_COST BODY: mangled cost
2.3 MANGLED_CABLE BODY: mangled cable
2.3 MANGLED_EXTNSN BODY: mangled extension(s)
Question:
1) Is there any way I can tell spamassassin to read the attachment
and score it with its rules
2) Is there a way I can use standard .cf rules to score just the
mime header portion of the mail. Eg rule
header LOCAL_HTML_NAME Content-Disposition =~ /name=\".*mag.*\.html?\"/
header LOCAL_HTML_ATACH Content-Disposition =~ /attachment/
I tried the above rule and I can't get it to "fire" with header or body.
3) Can i use mimedefang filters and call SA on the attachment?
I'm using canit-pro, sa 2.63.
