Dear Maintainer,
I'm unsure what lead to this, I've been having issues with Mail delivery on
localhost for a while now. I'm starting to get mails from Mail Delivery system
with the subject line of "Warning: Message 'Blah'delayed for 24 hours"
The body reads:
This message was created automatically by mail delivery software.
A message that you sent has not yet been delivered to one or more of its
recipients after more than 24 hours on the queue on localhost.

The message identifier is:     1o8Jxl-007SqX-3Q
The subject of the message is: popularity-contest submission
The date of the message is:    Mon, 04 Jul 2022 06:09:57 -0500

The address to which the message has not yet been delivered is:

  survey at popcon.debian.org
    Delay reason: lookup failed for all hosts in smarthost router:
    host_find_failed=ignore host_all_ignored=defer

No action is required on your part. Delivery attempts will continue for
some time, and this warning may be repeated at intervals if the message
remains undelivered. Eventually the mail delivery software will give up,
and when that happens, the message will be returned to you.

The mail Delivery report attachment reads:
Reporting-MTA: dns; localhost

Action: delayed
Final-Recipient: rfc822;survey at popcon.debian.org
Status: 4.0.0

email headers attachment reads:
From:   root <root at debiantim.midcoip.net>
To:     survey at popcon.debian.org
Subject:        popularity-contest submission
Date:   Mon, 04 Jul 2022 06:09:57 -0500

I don't have anything other than what Debian installs by Default for mail
programs, DNS. DHCP or anything else like that.

I have been having another issue where reading local mail in Evolution (version
3.44.2-1 )->On this Computer->Inbox causes my CPU to go to 100%.
I can't help but to wonder if the two are related?
Let me know what logs you need and how to get them and I'll be happy to send
