connect.com.au contact?

NetBSD.ORG's trouble-ticket system is currently being overwhelmed by
a virus attack facilitated by connect.com.au (which is bouncing viral
mail to forged From: addresses corresponding to trouble tickets at
NetBSD.ORG).

We don't want to have to dump all mail from connect.com.au; they seem
to have real users (some of whom participate in our mailing lists). Does
anyone have a contact there who might be able to correct the dumb
behaviour of their mail system?
