I confirm, you just need some good configuration for the MTA,
i.e. reject clients in spamlists, and so on.
and if you have resources, maybe greylist could help you rejecting
spam messages your remailer address will receive.

yes, but for unknown reasons, I've noticed some spam going out
from paranoia in the past.
Anyway, is not a big problem, I haven't received a single complaint
about spam.

but if you want to avoid wasting bandwidth,
a good solution for exit nodes is nilsimsa:

it needs some tweaks initially, and some time to check for false positive,
but it works quite well.
