My email was migrated from Postmaster (Spider Networks) to Zimbra about 2 months ago. Since then ex-Postmaster users have had bad gateway messages, Internal Server errors and now No Such Blob messages preventing access to any e-mails. Is this type of 'outage' usual with Zimbra/Vorari? If there are general problems with the Zimbra system, where does one find information about this - at the moment there are no messages anywhere I can find about this although 3 days ago a message was posted to the ex-Postmaster users at the log-in page apologising for the service. Even this has now disappeared. Can anyone help?
