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

smartin · Jan 19th 2022

Hi,

I'm using OMV 5.6.23-1.

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

Code

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.


For further assistance, please send mail to postmaster.


If you do so, please include this problem report. You can
delete your own text from the attached returned message.

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?

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

An internet search might help

In the shell:

Code

sudo postqueue -f

I did search for that error but couldn't find anything meaningful...

This is no error message, but an information.

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. plus.net refuses your authorization.
