Any chance that server is a forwarder for inbound mail?
If so, does it verify the user exists before accepting the message? Or does it
queue and let it bounce when it tries to forward the message?

There's NOTHING wrong with rejecting spam (ie: generating a 550 at the end of
the SMTP DATA phase).
Only post-delivery bouncing (ie: generating a DSN and sending it to the
Return-Path) is a bad idea for spam.
