Hi. This is the qmail-send program at bouncehost.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<name@domain.com>:
194.73.73.216 does not like recipient.
Remote host said: 550 <name@domain.com>... Relaying denied
Giving up on 194.73.73.216.

*********************************************

does this mean that the address doesn't exist or that its refusing to deliver it b'cos its spam?
