I did a quick check to see if my SpamAssassin Spam filter was
working. The result was that the filter is catching 99% of the Spam,
which makes up 96% of the email I receive. No messages were
incorrectly classified as Spam.
The Spam filter set up to delete high rating messages from the server
before they get to my computer. But I was curious to see how well
the filter was working. So I had the Spam rated messages put in a folder.
On Thursday morning I had 605 messages, of which 573 SpamAssassin
gave a Spam rating of higher than 2. I had a quick look through the
50 lowest rating of these, but did not find any which appeared to be
other than junk. I was therefore comfortable to delete all messages
with a rating of more than 2.
I then looked through the remaining 32 messages not rated as Spam by
the system. Of these, seven I considered to be Spam.
The Spam filter appears to be working very well. I could make it more
sensitive, but seven junk messages a day is acceptable.
ps: This does not include virus laden email. I was not willing to
turn off the virus filter, which deletes messages with virus
attachments before they get to the spam filter.
