What's your value of $sa_kill_level_deflt ?

In Debian default at least, a score of 7.287 reaches
$sa_tag2_level_deflt (4.0) so gets marked, but not $sa_kill_level_deflt
(10.0), so it won't get discarded (unless you do it later based on the
X-Spam headers, for example in procmail).

I'd suggest adding some SpamAssassin rules that catch it better.  Maybe try
* updating SpamAssassin;
* sa-update;
* check the SpamAssassin users list;
* see if ADVANCE_FEE_2_NEW rules are hitting anything;
* add your own scam rules;
* increase the value for Doppelstern.Scam4 in
@virus_name_to_spam_score_maps; or
* add more signatures in clamav-unofficial-updates.

Hope that helps
