http://noc.ntua.gr/~christia/tmp/KAUF-TIPP_DER_WOCHE.gzI get a few similar ones here, it may be the start of a spam run or
the fact that the stock spams morph so quickly. I haven't seen an
update from RDJ for stock spam in a while; I guess the authors have
real lives too so can't spend every waking hour fine tuning the rules
to catch each new iteration.
If I get persistent spam getting through with common features I write
my own rule and drop it in. It's often redundant within a few days so
gets morphed to catch the next ones that get through.
Perhaps you should go with your own rule and edit it as needed?
Looking at the other post on this thread you might want to check your
network tests.
