Bounce mail error

Hi, FTH2 Support Team:

I received a bounce email error message that says:
"Replies to forum posts are not accepted via e-mail. Please visit support.toastmastersclubs.org and post your reply there. Thank you."

I have no idea what does above message mean.

The message I sent using HTH2 addresses was:

To: members-XXXXXX@toastmastersclubs.org
Cc: admin-XXXXXX@toastmastersclubs.org ( this is to myself)

The message was distributed to members normally, so I suppose CC to club admin was something wrong.

Please let me know what the bounce error try to tell me.

You must have replied to a forum post notification.

You can ignore.

Thank you Brian.

So, can I understand that "Cc: admin-XXXXXX@toastmastersclubs.org" was nothing wrong?
Am I correct? I wonder why the message was not distributed to admin.

Let me report the subject line of the messages I dropped in my previous post.

The message I sent:
Subject: Club web site - Updated for new term
To: members-XXXXXX@toastmastersclubs.org
Cc: admin-XXXXXX@toastmastersclubs.org ( this is to myself)

The bounce message:
Subject: Message Not Delivered: Club web site - Updated for new term

check that the email address you have saved for admin-xxxxx is actually you club email address.

Admin address was correct. Same club number for both admin and members addresses.

This was a bug. Thanks for notifying us. It has been fixed.
