It can be used to run a DoS attach to your mail server. If you accept everything and the
you delegate sympa to reject the un-existent domains, you can easily take sympa to its
knees. Sympa has this stupid design where it want to be a bit MTA and a bit MDA.
I don't have a choice here, but I'd advice you to trow away sympa and use mailman that
has much better architecture.
