A "bounce", in terms of email, is when an email server has accepted mail
for delivery and then, later, found that the message is undeliverable.
That is, if the message can be rejected during the SMTP conversation,
then a bounce is not created, but if the server accepts the mail and
then, say, passes it on to a SPAM appliance which rejects the message,
then the server that accepted the message must send a message back to
the sender saying "I know I said I'd accept this, but I changed my
mind".
In your case, the reason for the bounce is listed on the web page
linked:
5.7.0 (COL004-MC1F52) Unfortunately, messages from (82.195.75.100) on
behalf of (yahoo.com) could not be delivered due to domain owner
policy restrictions.
570 is the SMTP rejection code. COL004-MC1F52 would appear to be an
error message identifier. You probably need to talk to hotmail.com (or
consult their help pages) to determine what the "policy restrictions"
are.
On the plus side, though, out of 16 mails sent to you by the debian
mailinglist server, only one has bounced. So either the problem has just
started, or you've had a glitch. You should get more messages if the
bounces continue, otherwise, assume the problem has fixed itself.
