The 550 message is a denial of permission to carry the message.

The person you're trying to contact is on a blacklist on the
mwall.cyberone.com.au server. Is your customer in Australia ?
They needn't be but between you and them, your email will be routed
through a number of differnt servers every time, depending on the
traffic, and if your recipients ISP is on the RBL on any of those, as
they are on cyberone.com.au then your email to them will be bounced
back at that point. They may not be responsible themselves but their
ISP may have been hacked. However if your email goes via a different
route another time as it might well do, then you could be lucky.


Here are some RBL details -

Short for Realtime Blackhole List, a list of IP addresses whose owners
refuse to stop the proliferation of spam. The RBL usually lists server
IP addresses from ISPs whose customers are responsible for the spam and
from ISPs whose servers are hijacked for spam relay.
