Same here. Lots of DNS errors for *.mail.protection.outlook.com ; sometimes hosts do resolve, but most of the time I see FORMERR (server doesn't support edns), SERVFAIL or connection timed out ... Looks like this already started on Jul 03, but errors increased over time. -- Thomas Mechtersheimer - Necklenbroicher Str. 45a - D-40667 Meerbusch - Germany EMail: [email protected] IRC-Nick: Mechti Of course I'm crazy, but that doesn't mean I'm wrong.
