This is perhaps a bit of a philosophical question as well as
a practical one. I have users sending me back mail that did not get trapped
as SPAM which it obviously is. Now when I look it up some of this stuff scores
really low (like 20 to 50% of the tag weight). It may not be on any blacklist,
it may have minimal text (mostly downloaded pictures) and so I do not catch it.
I see that I have a few options 1) Blacklist it
by sender but that is probably mostly a waste of time since the sender gets
spoofed and changes 2) Do nothing
and hope that it appears on more DNS tests so that it will trip more test and
then get caught (not a great option) 3) Consider
blacklisting the IP but that may not be possible if it is a major e-mail server
or may not be possible if it is a zombie 4) Look for
specific words/phrases in the body, subject etc and try filtering on that 5) Something
else, anything else?? It seems to me that these are my options and none of them
seem really definitive. Now maybe I am looking for something that doesn’t
exist but I thought I would ask here what others do. Any suggestions, thoughts etc would be appreciated. Thanx The |
