My post was confusing... sorry.  I am doing what you suggest above.

The difference is first I run a pile of mail (mixed ham/spam) thru,
just like it is normal mail.

Then from that result I pick out spam that was classified as ham and
ham classsified as spam.

Now I have two piles: 1 all spam and 1 all ham

Then I run the learning sessions from those mbox files.

My question were:

1) Does it matter that I have autolearn turned off in spamassassin
conf filt 'local.cf' while doing my sandbox work

2) I've dirived the mbox files of pure ham and pure spam by running
mixed mail so SA has already seen this mail.

Now that is sorted into known spam/ham can I use that same mail for
the learning sessions.
