      IE 11 copy/paste problem

      It has come to our attention that people using Internet Explorer 11 (IE 11) are having trouble with copy/paste to the forum. If you encounter this problem, using a different browser like Firefox or Chrome seems to get around the problem. We do not know what the problem is, but it seems to be specific to IE 11 and we are hopeful that Microsoft will eventually fix it.

You might want to state how long you have being using your spam filter, the typical amount of emails you get , the main types of filtering techniques used (bayesian, blacklists, reg exp etc.)


I'm looking for raw classification rates,

That is


number of successful classifications / total number of email.


So if you have 100 emails classified as 10 good and 90 spam, and 8 are classified wrongly (say 5 classified as spam are actually good, and 3 classified as good are actually spam) , your accuracy rate is (100-5-3)/100* 100% = 92%
