Between yesterday Tue 23rd Nov 07:27 and tonight Wed 24th Nov 01:48 several hundred emails have erroneously been flagged as spam by our mail server. Please check your SpamBox folder for potential false positives during that period.
While we are constantly updating our filtering rules to catch the nasty spam, we are always doing our best to avoid flagging real emails as spam. We apologize for this and are still investigating the details of the root cause. Because the bulk of the messages were being correctly delivered, it took us several hours before we noticed the problem and could fix it.
