[email protected] Not working?

[Safety0ff]

I have an issue that I need to resolve, but each time I email that address I get this error:

Hi. This is the qmail-send program at xxxxxx.com.
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.

[email protected]:
205.134.255.18 does not like recipient.
Remote host said: 550 No Such User Here"
Giving up on 205.134.255.18.

Can anyone confirm this or post the correct email?
-Thanks.

Should be working now, sorry.
