Spam classification

Question

Hello, 
 I have a few questions to Sophos Email Appliance. 
 I configured Sophos PureMessage for Unix in the past. PureMessage has the possibility to configure rules with the exact spam probability (in percent). Unfortunately with the appliance, I can only configure "High" and "Medium". Is there any way to configure this more precisely? We want to configure rules in 10 % steps. Each step will have a longer added Subject. Here is what we want to do to: 
 Spam probability = >50 % Subject = [PMX:#] Spam probability = >60 % Subject = [PMX:##] Spam probability = >70 % Subject = [PMX:###] Spam probability = >80 % Subject = [PMX:####] Spam probability = >90% Subject = [PMX:#####] 
 Also I want to know the exact classification of "High" and "Medium". Is there a percentage, that defines these two categories (like PureMessage)? Is there a possibility to edit "Medium" and "High"? 
 Regards

Unfortunately that is a limitation of the appliance vs pmx. 
 The medium spam rule triggers at 50% spam and the high spam rule is 90% You can not modify the values. 
 If you wish to have the spam scores printed in emails you could use a %%HITS%% or %%SPAM_REPORT%% in a banner or similar. For a complete list http://esa.sophos.com/docs/esa/sea_docs/en/ESA/concepts/PolAboutActionsTempVars.html

You would really not want to notify a spammer his message was rejected or dropped. (or provide any additional information to a would-be spammer) 
 The recommended method is to quarantine medium spam and discard high spam. 
 
 The other problem is you may end up getting yourself blacklisted in the process.
