Bug ID: 7087
Summary: Smaller HIT rate because of changes that affects URIBL
Product: Spamassassin
Version: 3.4.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Plugins
Assignee: dev@spamassassin.apache.org
Reporter: rafal.ramo...@eo.pl
I've been debugging why SA 3.4.0 is passing more spam than SA 3.3.2. I've found
that there were a bug #6700 where voters decided to disable functionality of
harvesting URIS from DKIM headers by commenting out code near line 2216 in
lib/Mail/SpamAssassin/PerMsgStatus.pm. Because URI's are not harvested they can
not be passed to URIBL (and maybe some other modules) which results in more
spam passing through. In some cases this reduced scoring by 8 points (by
hitting multiple block lists).
It would be nice if this functionality could be re-enabled. Maybe since this
functionality was disused in the past and there are some pro's and con's the
solution for this would be a configuration option to allow users to decide if
they want to harvest this uris or not? I would like to try to prepare a patch
if it could be included if future releases. If it is possible I'm open for
suggestions about name of configuration option or other requirements to
re-enable this functionality. Maybe there is other, better way of
re-implementation like placing it in URIBL plugin? I'm open for suggestions.
Best regards
Rafal Ramocki
