Okay, here's what I need ... I need a filter that will work in Sieve,
using the comparison extension discussed earlier, that will re-calculate
the score of an email message based on the message coming through as:
X-Spam-Status: Yes, hits=9.1 required=5.0 tests=FROM_ENDS_IN_NUMS,
MAILTO_TO_SPAM_ADDR,SUPERLONG_LINE,MAILTO_LINK,CHARSET_FARAWAY,
CTYPE_JUST_HTML,SUBJ_ALL_CAPS version=2.20
X-Spam-Flag: YES
X-Spam-Level: *********
X-Spam-Checker-Version: SpamAssassin 2.20 (devel $Id: SpamAssassin.pm,
v 1.77 2002/04/06 19:28:30 hughescr Exp $)
X-Spam-Prev-Content-Type: text/html; charset="ks_c_5601-1987"
SPAM: -------------------- Start SpamAssassin results ----------------------
SPAM: This mail is probably spam. The original message has been altered
SPAM: so you can recognise or block similar unwanted mail in future.
SPAM: See http://spamassassin.org/tag/ for more details.
SPAM:
SPAM: Content analysis details: (9.1 hits, 5 required)
SPAM: Hit! (1.0 point) From: ends in numbers
SPAM: Hit! (1.3 points) URI: Includes a link to a likely spammer email address
SPAM: Hit! (-0.4 points) BODY: Contains a line >=199 characters long
SPAM: Hit! (0.0 points) BODY: Includes a URL link to send an email
SPAM: Hit! (2.1 points) Character set indicates a foreign language
SPAM: Hit! (3.2 points) HTML-only mail, with no text version
SPAM: Hit! (1.9 points) Subject is all capitals
SPAM:
SPAM: -------------------- End of SpamAssassin results ---------------------
Now, let's say I'm a foreign language student ... I don't feel it is
appropriate for *my* email to have a weight of 2.1 assigned to it due to
"Character set indicates a foreign language", so wish to set that to 0.0
instead ... 'HTML-only email', I get quite regularly due to the high
number of Outlook users, so let's half its weight to 1.6 ... and I want my
threshold to be 7.5 instead of 5 ...
so, based on my personal changes, that email would score a 5.6, which
means it wouldn't be tagged as spam then ...
Now, if you can show me a way to write that with the comparison extensions
such that I can sell that to 5k+ students, staff and faculty as being
something "even an Outlook user" could write ... I'll be suitably
impressed ...
Of course, I could do this using the .spamassassin/userprefs configuration
file, but this won't work since there is no way for postfix to
differentiate users :(
