For the moment, use "Delete As Spam"/"Recover From Spam" for *any* mail that
appears in your 'Suspects' folder, and any spam that doesn't get identified,
and any ham that ends up in your 'Junk' folder (this last one should be
rare).  You can probably just continue doing that, and your results should
be fine - even though you don't get a balanced amount of mail, the
percentage of each ending up in your 'Suspects' folder will probably be much
closer to even.

If you do find that the imbalance is starting to get large (say > 5::1 or
1::5), then you could move some of the (spam/ham, whichever you have most
of) messages that end up in 'Suspects' straight to the 'Deleted Items'
folder/your inbox rather than training on them.  I suspect that this won't
be necessary, though, and the imbalance won't end up getting this high.

I hope this is starting to make sense!  (There is a lot of ongoing
discussion about the best way to train, and how to make that easiest for
users, so this should hopefully get simpler as time goes on).

No worries, glad to help.
