If they're sending bounces without an empty SMTP reverse-path, then
they're in violation of RFC2821 and common sense, and they're just a
mail loop waiting to happen. Report this to them and to the abuse
contact at their network provider.
I generally point out that further instances of this abuse will be
considered a deliberate denial-of-service attack and will be treated
accordingly.
It's a shame rfc-ignorant.org doesn't have a list for this. There are
quite a few vacation messages which behave similarly brokenly too.
