Issue:
Biology student attempts to e-mail assignment from a laptop.
IMail web interface - student e-mails to himself with assignment as an attachment (assignment3.wps)

syslog shows the email entering system - "message will be deleted"

09:26 14:42 SMTP(7479021f0000c548) probability email is spam 0.998035: email is spam

Question: are the statistical rules biased against the sciences or is something else wrong here...
This student currently can not submit Biology assignments via e-mail in Word or Works attachments - haven't tried any other tests as this behavior was simply too wierd to pass by...

What's Up?

The Premium Spam Filter out-of-box default settings were so good that I set the SPAM block to Autodelete.  I did run into a few friendlies being tagged as STAT FILTER block.  As a matter of fact the only STAT FILTER blocks I caught were friendlies.  So for now I have disabled the STAT FILTER block by setting it to No Action until I have a chance to dinker with it further.

Some folks come into the office and say its too hot <=> Others say it too cold

Some say they don't want the SPAM <=> Some say they still want their stationary and html nested tables and graphics

No win/win situation here
