Subject: 550 email client

I have a client who received this bounce: ('account' is not the real account name.)

Failed to deliver your message to
SMTP: Address rejected by host
Host '' says:
550 email client.

Now, I understand "Address rejected by host" -- there's no such email account on the server, but what does "550 email client." mean?
