I'm using OMV 5.6.23-1.
The notification system is sending me *dozens and dozens* of these emails:
This is the mail system at host openmediavault.local. I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

I'm guessing this is because I had to change my outgoing server from relay.plus.net 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?
