I'll need to check our logs to see what it looks like on ours, its been a while. But it is certainly *critical* that you have a map in Postfix to prevent it appearing in SMTP replies. I don't think Spamhaus would be too happy with people blurting out the "<OBFUSCATED>" to the public (or spammers). ;-)
