- What's the server hostname?
- Do you access the web via domain name 'easyvoicemail.nl'? like https://easyvoicemail.nl?
- Show us the full certbot command you used to request cert.

The original error says you don't have an A record for easyvoicemail.nl. But seems your hostname is NOT easyvoicemail.nl, please show us output of command "hostname -f".

Also, iRedMail doesn't allow you to use same hostname and mail domain name.

The original error says you don't have an A type DNS record for domain name "easyvoicemail.nl".

Yeah it does but there is a record as you saw before in our communication! So what to do?

You do not have them now under either domain - you must have removed them:

[root@plex ~]# dig +short ns easyvoicemail.nl.
v1.pcextreme.nl.
v2.pcextreme.nl.
v3.pcextreme.eu.
[root@plex ~]# dig +short a easyvoicemail.nl. @v1.pcextreme.nl.
[root@plex ~]# dig +short a easyvoicemail.nl. @v2.pcextreme.nl.
[root@plex ~]# dig +short a easyvoicemail.nl. @v3.pcextreme.eu.

I was showing you how I came to that conclusion and how *you* could test my results.  I did not say you should remove your nameservers.  Do you yourself a favor and when you don't know what a command does, read its' man page OR search for it online.   When you do, you'll see that the command I gave queries your nameservers for the "a" record of easyvoicemail.nl. - because no IP address was printed in the output, it means that no record was found.

To prove this to you another way which might be simplier for you to understand.  Put either of these into your web browser:

http://easyvoicemail.nl/
https://easyvoicemail.nl/

what happens?  You probably get an error because "easyvoicemail.nl" cannot be resolved in DNS.  Fix this first, then wait a 3 hours for DNS to propagate (as non-existent entries are commonly cached for 3 hours, ) then attempt to use certbot.
