Hi
On top of the Oracle Intelligent Advisor Forum, and maybe others, I see this

When I email that address with a question, I get this:
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
oracle-forums_moderators_us@oracle.com
host mxa-00069f01.gslb.pphosted.com \[205.220.165.26\]
SMTP error from remote mail server after RCPT TO:\<[oracle-forums\_moderators\_us@oracle.com](mailto:oracle-forums_moderators_us@oracle.com)\>:
550 5.1.1 Unknown recipient address.
Thank you for letting me know what the issue is - a permanent error, a spelling mistake or something else.
Regards
Richard
