Newb: Do I need to flush the Postfix mail queue? (If so, how)

  • Hi,

    I'm using OMV 5.6.23-1.

    The notification system is sending me *dozens and dozens* of these emails:

    I'm guessing this is because I had to change my outgoing server from to a new server a while ago and forgot to update the settings in OMV.

    Are there messages stuck in the mail queue which need flushing? How do I do this please? :)


  • as no answer was posted yet, I'd say its unlikely.

  • This is no error message, but an information.

    I'm sorry to have to inform you that your message could not
    be delivered to one or more recipients. It's attached below.

    postfix will take the mail out of the queue. Check the queue with mailq and it should be empty.

    If it is not, you can remove all deferred messages with postsuper -d ALL deferred

    And check your outgoing mail config. refuses your authorization.
