I would like to add to this conversation by asking what about after the
training? How do I get it to start discarding spam that fall into the
I used bogotrain.pl to train my database with a known set of spam and
ham. This worked great, however, I still get about 3 or so spam a day.
These are the spam with the funny text mixed in. For example:
draft alderman quasar arccos consortium caught eleventh bergen ache

I'm not exactly sure where I need to put the -o entry and what the
numbers should be. How do you decide what the values should be? There
is a reference to '-o 0.8,0.2' or something similar but I am not exactly

numbers were decided.
Thank you to those who wrote this program, because it limits my incoming
spam to just a few instead of 15 to 20 a day per account.
