The price hasn't changed yet. It will soon.
The message should have information on why it bounced. It's probably at your end.
Here's the entire message I received (everything below):
Hi! This is the ezmlm program. I'm managing the
mlist@listserver.jriver.com mailing list.
Messages to you from the mlist mailing list seem to
have been bouncing. I've attached a copy of the first bounce
message I received.
If this message bounces too, I will send you a probe. If the probe bounces,
I will remove your address from the mlist mailing list,
without further notice.
I've kept a list of which messages from the mlist mailing list have
bounced from your address.
Copies of these messages may be in the archive.
To retrieve a set of messages 123-145 (a maximum of 100 per request),
send an empty message to:
<mlist-get.123_145@listserver.jriver.com>
To receive a subject and author list for the last 100 or so messages,
send an empty message to:
<mlist-index@listserver.jriver.com>
Here are the message numbers:
