[Python-Dev] mail.python.org disruption

[ Mailed to python-dev and python-list, as that should cover most of the
users ;P ]

There was a slight disruption on mail.python.org this morning. For about
three and a half hours, it was rejecting most of its mail with the message:

Client host [....] blocked using singlehop.dsbl.org; Your mail has been
rejected because the server you are sending to is misconfigured.

The error means mail.python.org was using singlehop.dsbl.org as a DNSBL
list, but that list doesn't exist, so it rejects all mail. Someone (not me
:) added that blacklist at 08:15 local time (07:15 GMT) and I fixed it at
11:46 (10:46 GMT). Blame lingering PyCon-jetlag for me not catching it
earlier, sorry. About 7759 mails were bounced, although a decent portion of
them will have been actual spam (of which python.org gets massive amounts.)
If you sent legitimate mail in that period, and got a bounce back with a
message like the one above, it's safe to re-send it now.

Sorry for the inconvenience.
