Over the past few days I have been getting these emails daily

Subject: Anacron job 'cron.daily' on [host...]

A message that you sent has not yet been delivered to one or more of its

The message identifier is: 1pIgQ6-0002Nk-2L
The subject of the message is: Anacron job 'cron.daily' on host.[..]
The date of the message is: Fri, 20 Jan 2023 03:42:18 +0200

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

[e-mail here]

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.

@greektranslator - you'd want to check the connection from your server to that email address's mail server. I'd do that by doing the following:

Find where email is pointed:
dig mx
Then see if your server can connect to that mailserver:
telnet <domain or IP address output from above command> 25
If one of those tests fails, you wouldn't be able to send email to that address from your server.
