Nabble has no private message system. It uses ordinary email, so it is unlikely to be anything to do with Nabble directly.

More likely, one of your users has an attacked/compromised email account and it is their address book that has been harvested and is being used to send spam. The best you can do is probably to try to narrow down the user with the bad email address.
