Question on Mozilla junk mail controls

I understand mozilla mail has to "learn" which mail is junk...is this
done simply by clicking the junk icon in the inbox list? Does it matter
whether or not I move the unwanted to junk to another folder or delete
it AFTER marking it as junk?

....and if I understand correctly, once mozilla seems to be identifying
said mail on its own, I can then enable the auto removal of the junk
mail, correct?

Thanks!

 

Yes, or in any other folder.

you must not delete it, since the algorythm used requires to have all
the spams always to improve itself.

 

Good, I've been saving them in a junk folder.

Thanks for the info!

 

are you sure? mozilla has a built in function to delete junk mail after
XX number of days and there is a file called 'training.dat' which is the
training data for the Bayesian filter - so i don't think deleting the
actual emails will change the way the filter works.

 

The moz junk filter is based on the bayesian algorithm that requires the
original data. It incrementally creates a buffer (training.dat). Now,
the "delete old spams" features is created to get the most accurate
buffer possible (if you don't receive one type of spam il the last XX
months, it is likely that you won't received it anymore).
