Return to sender, that address unknown

6/21/2013: UO’s email servers have been blacklisted because someone was sending spam. As usual, The King has the best explanation of the technical details, or see http://pages.uoregon.edu/status/reports.cgi for the layman’s version, which says you should have got a bounce message if any messages you sent were “returned to sender”. Apparently you can do a work around by using your regular email program and setting gmail as your outgoing server. This has been going on for a week or so, I don’t understand why they didn’t send out an email notifying people and telling them how to fix it.
